How many days until the next Worm Moon?
The Worm Moon is the traditional name for the full moon that occurs in March. It is associated with the return of earthworms, thawing soil, and the first signs of spring in the Northern Hemisphere. Unlike a fixed holiday, it does not fall on the same calendar date every year.
The next Worm Moon depends on the date when you check, your time zone, and which annual occurrence you mean. After the March 14, 2025 full moon, the next one occurs on March 3, 2026. From any date before March 3, 2026, count the complete days between today and that date to find the remaining wait.
A calendar countdown can differ by one day if the astronomical full moon happens near midnight locally. For a practical answer, use the local date of the full moon rather than relying only on the Universal Time listed by an astronomy source.
Why the March full moon is called the Worm Moon
The name comes from seasonal observations traditionally associated with March. As the ground softens, earthworms become more active, attracting birds and signaling the approach of spring. Some sources connect the name with beetle larvae or other creatures emerging from winter shelter.
Worm Moon is a cultural nickname, not a separate astronomical type of moon. Astronomers classify the event as a full moon, which happens when the Moon lies opposite the Sun from Earth and its visible side is fully illuminated.
Other traditional names may be used for the same March full moon, depending on region and cultural tradition. The name can therefore be useful for seasonal planning, but the exact date is determined by the lunar cycle.
The next Worm Moon dates
The lunar cycle lasts about 29.5 days, so full moons move through the calendar from year to year. A March full moon can occur early in the month, near the middle, or late in March. In some years, a March calendar month can contain two full moons, although the second is usually given a different seasonal nickname.
The following dates show a useful sequence for planning. Exact times can vary by source because of rounding and time-zone conversion.
| Year | Worm Moon date | Weekday | Approximate gap from the previous one |
|---|---|---|---|
| 2025 | March 14 | Friday | 12 months |
| 2026 | March 3 | Tuesday | 354 days |
| 2027 | March 22 | Monday | 384 days |
| 2028 | March 11 | Saturday | 355 days |
| 2029 | March 1 | Thursday | 356 days |
The 2026 date is especially important for anyone asking about the next Worm Moon after the 2025 event. If the date you are checking is after March 3, 2026, the next occurrence is March 22, 2027.
How to calculate the countdown
To calculate the number of days remaining, identify today’s date and the local calendar date of the next Worm Moon. Then subtract the earlier date from the later date. If today is March 1, 2026, for example, March 3 is two calendar days away.
The calculation should exclude the starting date when describing a standard countdown. Thus, a full moon on March 3 is one day away on March 2 and two days away on March 1. Some countdown tools count the current day as part of the result, so check the counting method before comparing answers.
Year length also affects the result. A common year has 365 days, while a leap year has 366. For quick calendar checks, resources such as the April day count can help verify month lengths when a countdown crosses from one month into another.
Time zones and the full moon date
A full moon occurs at one precise moment, but that moment can fall on different local dates around the world. For example, an event recorded in Coordinated Universal Time during the early hours of March 4 may still be March 3 in a North American time zone.
This distinction matters when the question is how many days until the Worm Moon. A countdown based on UTC may show a different remaining number from one based on local midnight. For a personal observation plan, use the date and time displayed for your location.
The Moon can also look full on the nights immediately before and after the exact peak. If the astronomical moment occurs during daylight, the best visible evening may be the night before or the night after, depending on location and weather.
Worm Moon versus the spring equinox
The Worm Moon is not the same event as the spring equinox. The equinox marks the point when day and night are nearly equal in length, usually around March 20 in the Northern Hemisphere. The March full moon can occur several weeks before or after it.
This distinction explains why the Worm Moon sometimes appears early in March and sometimes late in the month. The full moon follows the lunar cycle, while the equinox follows Earth’s yearly orbit around the Sun. Their dates are related to the season but are calculated independently.
For gardening, photography, or outdoor events, it can be useful to record both dates. The full moon provides a bright nighttime landmark, while the equinox offers a solar marker for the changing season.
Planning a Worm Moon observation
The full Moon rises around sunset and sets around sunrise, though the exact times vary by location and date. A clear horizon makes moonrise easier to see, especially when photographing the Moon near trees, buildings, or hills.
Useful preparation includes:
- Check the local moonrise and moonset times.
- Confirm the full moon date in your time zone.
- Choose a location with a clear eastern horizon for moonrise.
- Allow for cloud cover, terrain, and nearby artificial light.
- Use the surrounding nights if the exact peak occurs during daylight.
The Moon may appear especially striking when it is low above the horizon, but the familiar enlarged appearance is largely a visual effect. A phone or camera with a stable support can still capture a detailed image when exposure and focus are set carefully.
A countdown is most accurate when it uses a definite location, date, and time zone. For a simple calendar answer, count to the local date of the full moon; for an observation plan, include the exact time and expected moonrise.
Check the upcoming full-moon date, subtract today’s date, and mark the evening on your calendar. The Worm Moon offers a dependable seasonal reminder, even though its position in March changes each year.
