2027 Lunar Almanac Northern Edition

Year at a glance

Every principal Moon phase of 2027, in UTC. To convert to local time, add your offset: Alaska UTC-9, Pacific UTC-8, Mountain UTC-7, Central UTC-6, Eastern UTC-5, Atlantic UTC-4, Newfoundland UTC-3:30, UK UTC+0, Australian Eastern UTC+10. These are standard-time offsets; in daylight saving time add one hour (Newfoundland becomes UTC-2:30).

Within a row, each column lists that phase on its own, so the dates are not always in order across the row (for example, September’s New Moon is on Sep 30 but its First Quarter is on Sep 7).

Eclipses, supermoons and apsides

Eclipses

Supermoons and micromoons

A supermoon is usually discussed for full Moons, when a nearby Moon looks a little larger and brighter. Applying the term to new Moons is a wider convention: a new Moon cannot be seen, but it marks a Moon near perigee. The thresholds are this almanac’s own, and other sources use different cutoffs.

Perigee and apogee

Distances are measured from the centre of the Earth to the centre of the Moon.

Sun and seasons

Equinoxes and solstices are the same instant everywhere on Earth. Which season begins depends on your hemisphere.

Earth and the Sun

Earth is closest to the Sun in early January, during the northern winter. The seasons come from the tilt of Earth’s axis, not from its distance from the Sun.

The Sun and the Moon’s path

Because a Full Moon sits opposite the Sun, the Full Moon climbs high in the winter sky and rides low in summer, the reverse of the Sun. The Harvest Moon is the Full Moon nearest the September equinox. In 2027 that is Sep 15, 8 days before the equinox on Sep 23. Around the autumn equinox (September for the Northern Hemisphere), the Moon rises at a shallow angle to the horizon, so it rises only a little later each night for several evenings in a row.

Your hemisphere

This is the Northern Hemisphere edition. Season names for both hemispheres are listed, so the table works for readers anywhere.

Lunar orbit and eclipse seasons

The Moon’s orbit is tilted about 5.1 degrees to the ecliptic, the Sun’s apparent path. The two points where the orbit crosses the ecliptic are the nodes: the ascending node, where the Moon crosses going north, and the descending node, where it crosses going south. An eclipse can happen only when a New Moon (solar eclipse) or Full Moon (lunar eclipse) falls close to a node. That is why eclipses do not happen every month: most months the Moon passes above or below the Sun’s path.

The nodes slide slowly westward around the ecliptic, once every 18.6 years. So the Sun reaches a node about 173 days apart, and each year the eclipse seasons arrive about 19 days earlier. Solar eclipses are possible when the Sun is within about 18 days of a node, lunar eclipses within about 12 days.

Eclipse seasons

Node crossings (UTC)

Declination and lunation lengths

Declination is the Moon’s angle north or south of the celestial equator. It sets how high the Moon climbs, where it rises and sets, and how long it stays up. In 2027 the Moon’s declination ranges from -27.7 to +27.7 degrees. This range itself swells and shrinks over an 18.6-year cycle. At a major lunar standstill, last reached around 2024 and 2025, the range is widest, close to 29 degrees either way. At a minor standstill, due in the 2030s, it narrows to about 18 degrees.

Lengths of the lunations

A synodic month, New Moon to New Moon, averages 29.53 days but varies. The shortest this year is 29.29 days and the longest 29.81 days.

Lunar calendar dates

Festivals whose dates are set by the Moon, for 2027. Jewish holidays begin at sunset on the evening before the date shown. Islamic dates are expected dates, and Islamic, Hindu and Buddhist dates can move by a day or two with local sighting or region. Easter, Passover and Hebrew dates are calculated by rule, and Chinese dates use the New Moon in UTC+8.

Eclipse guide

Feb 6, 16:00 UTC. Annular solar eclipse (Saros 131)

The Moon is relatively far from Earth (402,700 km at new moon), so it cannot fully cover the Sun and leaves a ring. Eclipse magnitude 0.928, annularity up to 7 min 51 s, path about 282 km wide. Greatest eclipse is in the South Atlantic (31.3°S, 48.5°W). The annular path passes over South America. The eclipse is not visible from North America.

Feb 20, 23:13 UTC. Penumbral lunar eclipse (Saros 143)

Penumbral magnitude 0.927 and umbral magnitude -0.057, so the Moon just misses the dark umbra. The penumbral phase runs 21:12 UT to 01:13 UT on Feb 21. At greatest eclipse the Moon is overhead at 10°N, 15°E over central Africa, so Africa and Europe are best placed. The Moon is also above the horizon from western and southern Asia and from the Atlantic side of the Americas, including New York. The shading is subtle and easiest to notice near maximum.

Jul 18, 16:03 UTC. Penumbral lunar eclipse (Saros 110)

Extremely shallow. The penumbral magnitude is only 0.0014 and the umbral magnitude -1.068. The penumbral phase lasts about 12 minutes (15:57 to 16:09 UT), so the Moon shows no noticeable change. The Moon is overhead at 22°S, 121°E over Australia. The eclipse is not visible from North America.

Aug 2, 10:07 UTC. Total solar eclipse (Saros 136)

The Moon is close to Earth (357,375 km at new moon). Eclipse magnitude 1.079, totality up to 6 min 23 s, path about 258 km wide, with greatest eclipse at 25.5°N, 33.2°E near Luxor, Egypt. It is the longest total solar eclipse between 1991 and 2114. Totality crosses southern Spain, Morocco, Algeria, Tunisia, Libya, Egypt, Sudan, Saudi Arabia, Yemen and Somalia. A partial eclipse is seen across Europe, Africa, the Middle East and western Asia. It is also seen from Iceland, Ireland, Great Britain, southern Greenland, northern Maine and eastern Canada, including Newfoundland and the Atlantic Provinces, shortly after sunrise (in Canada it starts around 5:36 NDT).

Aug 17, 07:14 UTC. Penumbral lunar eclipse (Saros 148)

Penumbral magnitude 0.546 and umbral magnitude -0.525. The penumbral phase runs 05:24 to 09:03 UT. The Moon is overhead at 12°S, 108°W over the eastern Pacific, so the Americas and the Pacific are best placed, including North America. A faint shading on one side of the Moon may be noticeable near maximum.

Saros series

Eclipses repeat in families called Saros series, about 18 years 11 days apart. Each eclipse above belongs to a numbered series, shown in its heading. Magnitudes, Saros numbers and phase times come from NASA’s Eclipses During 2027 page.

Moon and planet meetings

Selected close approaches: the Moon within 5 degrees of Mercury, Venus, Mars or Jupiter, and within 3 degrees of Regulus, Spica, Aldebaran or the Pleiades. A conjunction is the moment the Moon and the object share the same ecliptic longitude. It is a calculated instant and can differ slightly from the moment of closest approach. Gaps are geocentric, measured from the centre of the Earth, so from your location the gap differs by up to about 1 degree. Where the Moon passes within 1.2 degrees, an occultation may be visible from some part of the Earth. That is only a screening test: it needs the observer to be inside the occultation’s visibility zone. Occultations of stars are in the next section.

Passes closer than 15 degrees to the Sun are left out. Mercury and Venus are often low in twilight. Occultations of Antares are not repeated here.

Lunar occultations

An occultation is the Moon passing in front of a star or planet. The Moon moves eastward against the stars, so the object disappears at the Moon’s eastern limb and reappears at its western limb. With a waxing Moon that means it disappears at the dark limb, which is easy to time, and reappears at the bright limb. With a waning Moon it is the other way round. A grazing occultation is one where the object just skims the limb and blinks in and out among lunar mountains. It is visible only along a path a few kilometres wide.

These are the passes where the Moon gets within 1.2 degrees of the object, or 2 degrees of the Pleiades cluster. Gaps are geocentric, so each is only a screening test: an occultation is seen only from the region of Earth the Moon’s shadow track crosses, and your location decides whether you are in it. For local times and paths, use occultation prediction software or the International Occultation Timing Association.

Planetary events of 2027

When each planet is best placed. At opposition a planet is opposite the Sun, rises at sunset and is at its brightest and closest. Mercury and Venus are best seen near their greatest elongations, when they are farthest from the Sun in our sky. Dates are in UTC.

Dark skies and meteor showers

A dark-sky window is a run of nights when the Moon is under 25 percent lit, so moonlight does little to wash out faint objects. The very dark nights have the Moon under 5 percent lit.

These windows use the Moon’s illumination at 12:00 UTC each day. They are date ranges, not a guarantee of dark skies at your location. Local moonrise and moonset decide how much moonlight reaches you on a given night, and twilight, cloud, haze and light pollution matter as well.

Meteor showers

Peak times for these meteor showers follow the International Meteor Organization’s 2027 calendar and are usually good to within a day or so. ZHR is the zenithal hourly rate: the number of meteors an ideal observer would see in perfectly clear, dark skies with the radiant overhead. The counts you actually see are usually lower. The Moon column is how lit the Moon is at the peak time, or at midday UT when the IMO gives no time.

Minor showers

Tides

The Moon and Sun raise the tides. Spring tides, with the largest range between high and low water, come around every New Moon and Full Moon. Neap tides, with the smallest range, come around the First and Last Quarters. When a New or Full Moon falls near perigee, the Moon’s stronger pull gives a perigean spring tide, with higher highs and lower lows than usual.

These are the New and Full Moons within 48 hours of perigee. The timing is the gap between the two events.

Before you rely on it

The heights and times of real tides depend on your coastline, the weather and air pressure. Use your national tide tables, such as NOAA in the United States or the Canadian Hydrographic Service in Canada, for local predictions. Live tide charts are on moonphase.today.

Libration

Libration is the Moon’s slow rocking, which lets observers see about 59 percent of its surface over time. Near the extremes below, craters along that edge of the disc are tilted into better view. Values are in degrees. Positive latitude tips the north pole toward Earth and negative tips the south pole.

Earthshine and the Lunar X

Earthshine is the faint glow on the dark part of a thin crescent Moon, sunlight bounced off Earth. It is best seen when the crescent is between about 1 and 20 percent lit, in a dark sky, and is visible to the eye or with binoculars.

The Lunar X

The Lunar X, also called the Werner X, is a feature that forms where sunlight catches the rims of three craters, with the Lunar V nearby. It is visible through binoculars or a small telescope for about 4 hours around First Quarter. The best start time shifts by a couple of hours from month to month with libration. Check that the Moon is up at your location at that time. First Quarter times:

Understanding lunar phases

The Moon takes about 29.53 days to go from one New Moon to the next (the synodic month). Twelve of these add up to about 354 days, which is why each phase falls on different calendar dates from year to year.

Phase is not the same as visibility

Phase times in this almanac are exact astronomical instants, the same moment everywhere on Earth. Whether you can see the Moon at that moment depends on where you are, because moonrise and moonset vary with latitude and longitude. A Full Moon can happen while the Moon is below your horizon. A New Moon is not the only dark time either: the days around it have a thin crescent that sets early. For rise and set times, use the moonrise tool on moonphase.today.

Illumination

The percentage on each calendar day is the share of the Moon’s disc, as seen from Earth, that is lit by the Sun. It is not the share of the Moon’s whole surface.

Moon names and distances

Traditional Full Moon names were popularized by North American almanacs and draw on Native American, colonial and European traditions. They vary between cultures and are not official astronomical designations.

Lunar distance

The Moon’s orbit is an ellipse. Perigee is the closest point and apogee the farthest. In 2027 perigee ranges from about 357,000 to 370,000 km and apogee from about 404,000 to 407,000 km. All distances here are measured from the centre of the Earth to the centre of the Moon, not from the surface. A Full Moon at perigee can look up to about 14 percent wider and 30 percent brighter than one at apogee.

Supermoons and micromoons

This almanac calls a full or new Moon within 360,000 km a supermoon and one beyond 405,000 km a micromoon. There is no official cutoff, so other sources may list different dates. The term is mainly used for Full Moons. For New Moons it is a wider convention, since a New Moon cannot be seen, but it marks a Moon near perigee.

Apparent size of the Moon

The closest Full Moon looks about 14 percent wider than the farthest. That is a change in angular size, how wide the Moon appears, not in its physical diameter of about 3,475 km.

Folklore and traditions

Planting by the Moon

Planting by lunar phase is a longstanding agricultural tradition. Scientific evidence that lunar phases independently improve crop growth or yields remains insufficient. Gardeners in the almanac tradition plant crops that grow above ground, such as leafy greens, grains and beans, while the Moon is waxing, from New Moon to Full Moon. They plant root crops and bulbs, and do pruning and weeding, while the Moon is waning, from Full Moon to New Moon.

Fishing and hunting

Solunar lore says fish and game are most active when the Moon is overhead or underfoot (major periods, about 2 hours) and at moonrise and moonset (minor periods, about 1 hour), strongest near New and Full Moons. The periods depend on your location, so none are printed here. The solunar fishing calendar and solunar hunting calendar on moonphase.today calculate them for any place.

Glossary

Notes and method

Time and precision

Every time is UTC, rounded to the nearest minute. Dates are rounded to the day, distances to the nearest kilometre, angles to a tenth of a degree and libration and declination extremes to the nearest hour. A phase is the same instant everywhere, but the calendar date can differ by a day depending on your time zone.

Calculations

Phases, distances, eclipse peaks, libration, declination, nodes, planetary events and conjunctions were computed with Astronomy Engine (Python version 2.1.19) on November 4, 2026. In spot checks against the US Naval Observatory table, phase times matched to within one minute, usually running one minute later. For official reference instants, use the USNO table.

Seasons and apsides

Equinox, solstice, perihelion and aphelion times are the US Naval Observatory’s published values. Perihelion and aphelion times differ by a few minutes between sources, because Earth’s distance from the Sun changes very slowly near those points.

Eclipses

Magnitudes, Saros numbers, phase times and greatest-eclipse locations are from NASA’s Eclipses During 2027 page, retrieved November 4, 2026. NASA shows visibility regions as maps only, so the written regions come from timeanddate.com and other published eclipse summaries, and the Moon’s position at greatest eclipse.

Geocentric positions

Conjunctions and the planet-meeting tables use apparent geocentric positions, corrected for aberration, with the Moon measured from the centre of the Earth. Observers see the Moon shifted by up to about 1 degree against the background (topocentric parallax). Distances are geometric, centre to centre. Occultations are screened at 1.2 degrees (2 for the Pleiades), which says an occultation is possible somewhere, not where.

Daily illumination and hemisphere

Percentages and Moon drawings use the Moon’s position at 12:00 UTC. The drawings are standardized Northern Hemisphere views. In the Northern Hemisphere the lit side of a waxing Moon is on the right. The orientation also shifts with your latitude.

Calendar dates (cultural, not astronomical)

These are predictions from calendar rules, not astronomical events. Easter uses the standard Gregorian and Julian rules, and Hebrew dates use the pyluach library. Islamic dates use the Umm al-Qura calendar through the hijri-converter library, and match published expectations, but the actual dates depend on local moon sighting. Chinese dates use the New Moon in UTC+8: New Year is the second New Moon after the December solstice, and Mid-Autumn is day 15 of the lunar month that holds the September equinox. Hindu and Buddhist dates are from published panchang calendars and vary by region.

Meteor showers

Peak times, ZHR values and the minor showers follow the IMO 2027 Meteor Shower Calendar, retrieved November 4, 2026. The Moon column is computed here.

Dark skies, tides, planets

Dark windows use the Moon’s illumination at 12:00 UTC. Perigean spring tides are New or Full Moons within 48 hours of perigee, and strongest within 24 hours. Opposition and conjunction times are from geocentric ecliptic longitudes, and greatest elongations from Astronomy Engine’s search.

Libration, earthshine, Lunar X

Libration extremes are the greatest tilts of the Moon’s sub-Earth point. Earthshine ranges use days when the Moon is 1 to 20 percent lit. The Lunar X is visible for about 4 hours around First Quarter, with the exact timing varying with libration.
