When Is Full Moon – 2026 Calendar Dates and Times

For those tracking lunar cycles, knowing when the next full moon occurs provides essential timing for everything from stargazing plans to cultural traditions. The full moon calendar for 2026 contains thirteen opportunities to observe our nearest celestial neighbour at its most luminous.

Each full moon carries its own traditional name, often rooted in agricultural cycles or seasonal markers. Understanding the precise dates and times helps observers across different time zones plan their viewing sessions effectively. Whether checking if tonight presents a full moon or planning ahead for specific months, having accurate data at hand makes all the difference.

When Is the Next Full Moon?

The most recent full moon occurred on May 1, 2026, known as the Flower Moon. The next upcoming full moon arrives on May 31, 2026, a relatively rare occurrence sometimes referred to as the Blue Moon. This second appearance of a full moon within the same calendar month creates a distinctive event in the lunar cycle.

Full Moon Calendar 2026

The complete list of full moons for 2026 provides dates, traditional names, and precise timing for observers worldwide. Times listed in Eastern Daylight Time (EDT) can be converted to other time zones using standard time zone conversions.

First Quarter of 2026

The year opens with the Wolf Moon on January 3 at 5:03 a.m. EDT, followed by the Snow Moon on February 1 at 5:09 p.m. EDT. March brings the Worm Moon on March 3, which coincides with a total lunar eclipse, making it a particularly significant event for skywatchers. The total lunar eclipse during the Worm Moon offers an exceptional viewing opportunity for those with clear skies on that date.

Second Quarter of 2026

April features the Pink Moon on April 1 at 10:12 p.m. EDT. May stands out as a remarkable month with two full moons. The Flower Moon arrives first on May 1 at 1:23 p.m. EDT, followed by the Blue Moon on May 31 at 4:45 a.m. EDT. This double appearance of a full moon within a single calendar month represents a relatively rare phenomenon. The Strawberry Moon on June 29 at 7:57 p.m. EDT closes the second quarter.

Third Quarter of 2026

The Buck Moon appears on July 29 at 10:36 a.m. EDT, transitioning into the Sturgeon Moon on August 28 at 12:19 a.m. EDT. Notably, August 28 also features a partial lunar eclipse during the Sturgeon Moon. September brings the Corn Moon on September 26 at 12:49 p.m. EDT, connecting to agricultural traditions in the Northern Hemisphere.

Fourth Quarter of 2026

October features the Hunter’s Moon on October 26 at 12:12 a.m. EDT. The Beaver Moon arrives on November 24 at 9:54 a.m. EDT, traditionally associated with the time when beavers finish building their winter lodges. December closes the year with the Cold Moon on December 23 at 8:28 p.m. EDT, marking the longest nights of the year.

What Moon Phase Are We In Right Now?

Determining the current moon phase requires understanding the progression between full moons. A complete lunar cycle, called the synodic month, lasts approximately 29.5 days. Between each full moon, the moon passes through distinct phases: waning gibbous, last quarter, waning crescent, new moon, waxing crescent, first quarter, and waxing gibbous before reaching fullness again.

Those checking whether tonight presents a full moon should consult reliable sources such as NASA’s moon phase resources or the United States Naval Observatory’s lunar data. These authoritative sources provide current phase information updated regularly.

The progression of moon phases follows a predictable pattern, though exact timing varies slightly due to the moon’s elliptical orbit and varying distance from Earth. At apogee, when the moon reaches its farthest point from our planet—approximately 252,177 miles away on May 4, 2026—the lunar disc appears slightly smaller, though this difference remains barely perceptible to casual observers.

Understanding Waxing and Waning

When the moon moves toward fullness, it enters the waxing phase. Waxing crescent occurs when the illuminated portion grows from a thin sliver to roughly half. The waxing gibbous phase follows, with the bright portion expanding until the full moon arrives. After the full moon, the process reverses during the waning phase, with the illuminated portion shrinking progressively.

How Often Does a Full Moon Occur?

Full moons occur roughly once every 29.5 days, meaning most years contain twelve full moons—one per month. However, because this cycle falls slightly short of a full calendar month, occasionally a year experiences thirteen full moons. The year 2026 exemplifies this phenomenon with its thirteen full moon events.

Factors Affecting Full Moon Frequency

Several astronomical factors influence when full moons occur. The moon’s elliptical orbit means its speed varies throughout each revolution—moving faster when closer to Earth and slower at apogee. This variation causes the synodic month to fluctuate by several hours, occasionally resulting in two full moons within a single calendar month.

Additionally, calendar boundaries play a role. A full moon appearing in the final days of any month increases the likelihood of a second full moon occurring in the following month. The positioning of months with 30 or 31 days versus February’s shorter duration further complicates the pattern.

The Blue Moon Phenomenon

The Blue Moon on May 31, 2026 represents this calendrical curiosity. While the name suggests a blue colour, atmospheric conditions rarely cause the moon to appear tinted blue. The term has evolved through historical misinterpretations, originally arising from a 1946 magazine error regarding seasonal Blue Moons. Today, the most commonly referenced definition refers to the second full moon in a calendar month.

Notable Celestial Events in 2026

Beyond the regular full moons, 2026 presents two lunar eclipses coinciding with full moon events. These eclipses offer remarkable viewing opportunities for observers equipped with appropriate viewing methods.

March 3: Total Lunar Eclipse

The Worm Moon on March 3 arrives accompanied by a total lunar eclipse. During a total lunar eclipse, Earth positions itself directly between the sun and moon, casting Earth’s shadow across the lunar surface. Observers may witness the moon taking on reddish-orange hues as sunlight bends through Earth’s atmosphere—a spectacle sometimes called a blood moon.

August 28: Partial Lunar Eclipse

The Sturgeon Moon on August 28 features a partial lunar eclipse. During partial eclipses, only a portion of the moon passes through Earth’s umbra—the darkest part of its shadow. The visible portion varies depending on the precise alignment of celestial bodies.

Understanding Full Moon Names

Traditional full moon names reflect the rhythms of agricultural life and seasonal changes. These naming conventions, developed by Native American tribes and later adopted by colonial settlers in North America, connected lunar cycles to practical activities. The Space.com full moon calendar provides comprehensive listings of these traditional names.

The Wolf Moon in January acknowledges the winter months when wolf packs howled near settlements. The Snow Moon follows in February, marking typically the heaviest snowfall. Spring brings the Worm Moon in March, symbolizing earthworm activity as soil thaws, followed by the Pink Moon in April named after pink wildflowers.

May’s Flower Moon celebrates blooming flowers, while June’s Strawberry Moon signals strawberry harvesting season. Summer months feature the Buck Moon in July—named for growing deer antlers—and the Sturgeon Moon in August when sturgeon fish proved most catchable. The Corn Moon in September and Hunter’s Moon in October connect to autumn harvesting and hunting activities.

Late-year moons include the Beaver Moon in November, traditionally the time for trapping beavers before winter freeze, and the Cold Moon in December, acknowledging the onset of harsh winter conditions. These names endure because they capture observable natural patterns that remain relevant across generations.

Summary: When Is the Next Full Moon?

The next full moon arrives on May 31, 2026, designated as the Blue Moon due to being the second full moon in May. Those seeking to determine whether tonight presents a full moon can reference the comprehensive full moon calendar for accurate timing information. With thirteen full moons throughout 2026 and two lunar eclipse events, the year offers abundant opportunities for lunar observation. Understanding the roughly 29.5-day lunar cycle helps predict upcoming phases, while traditional full moon names connect modern observers to centuries of celestial observation traditions.
