When Is the March New Moon
The March new moon is the first lunar phase of the month, when the Moon sits roughly between Earth and the Sun. Its exact date changes each year because the lunar cycle lasts about 29.5 days.
In 2025, the March new moon occurs on March 29. In other years, it can fall anywhere from late February to late March, depending on the alignment of the Sun, Earth, and Moon.
Why the Date Changes Every Year
The lunar calendar follows the Moon’s orbit, which is slightly shorter than the solar year. Because of this, the new moon date shifts annually. Time and Date provides detailed moon phase tables for each year.
What the March New Moon Means
The new moon marks the start of the lunar month in many calendars and can influence tidal patterns. It is also used as a reference point for religious and cultural observances tied to lunar cycles.
