About the Easter Date Calculator
The Easter Date Calculator is a specialized tool that determines the date of Easter Sunday for any given year, along with the dates of related observances in the Christian calendar. Easter is a "moveable feast," meaning its date changes each year based on a complex calculation involving the lunar calendar.
Understanding Easter's Date
Easter Sunday is celebrated on the first Sunday after the first full moon that occurs on or after the spring equinox (around March 21). This means Easter can fall anywhere between March 22 and April 25 in the Western Christian tradition. Our calculator uses the accurate algorithm for determining this date.
The Easter Algorithm
The formula used in this calculator is based on the Butcher's algorithm, which provides accurate Easter dates for years between 1583 and 4099. This range covers the implementation of the Gregorian calendar in 1582 and extends far into the future, ensuring reliable calculations for practical purposes.
Related Easter Dates
Beyond Easter Sunday itself, our calculator provides dates for other significant days in the Easter season:
- Ash Wednesday - Marks the beginning of Lent, the 40-day period of fasting and preparation (46 calendar days before Easter).
- Palm Sunday - Commemorates Jesus's triumphal entry into Jerusalem (one week before Easter).
- Good Friday - Remembers the crucifixion of Jesus (two days before Easter).
- Ascension Thursday - Celebrates Jesus's ascension into heaven (40 days after Easter, counting Easter itself).
- Pentecost Sunday - Commemorates the descent of the Holy Spirit (50 days after Easter, counting Easter itself).

- Long-term calendar planning
Whether you're planning a religious observance, coordinating events, or simply curious about when Easter falls in a particular year, our Easter Date Calculator provides accurate and comprehensive information for your needs.
Frequently Asked Questions
Easter's date varies because it follows a lunisolar calendar, not the standard Gregorian calendar. The First Council of Nicaea in 325 CE established that Easter would be celebrated on the first Sunday after the first full moon occurring on or after the spring equinox. This means Easter can fall anywhere between March 22 and April 25 in the Western Christian tradition.
No. While Western Christianity (Roman Catholic, Protestant, etc.) uses the Gregorian calendar for calculating Easter, Eastern Orthodox churches typically use the Julian calendar, which can result in Easter being celebrated on a different date. The difference can be up to five weeks. Our calculator uses the Western Christian (Gregorian) method.
In the Western Christian tradition (using the Gregorian calendar), Easter can fall as early as March 22 and as late as April 25. The last time Easter fell on March 22 was in 1818, and it won't happen again until 2285. The last time it fell on April 25 was in 1943, and it will next occur in 2038.
Our calculator uses the Butcher's algorithm, which provides accurate Easter dates for years between 1583 and 4099. This range begins just after the implementation of the Gregorian calendar in 1582 and extends far enough to cover all practical purposes. Beyond this range, additional astronomical factors might need to be considered for extreme accuracy.
Ash Wednesday marks the beginning of Lent, the 40-day period of fasting, prayer, and penitence before Easter in many Christian denominations. It falls 46 calendar days before Easter Sunday (40 days not counting Sundays). The name comes from the practice of placing ashes on the foreheads of worshippers as a sign of repentance.
Pentecost Sunday is celebrated 50 days after Easter (counting Easter itself as day 1), or 49 days after Easter Sunday. Ascension Thursday is celebrated 40 days after Easter (again counting Easter itself), commemorating Jesus's ascension into heaven. Both dates are directly tied to Easter and move with it each year.
Yes! This calculator is excellent for long-term planning. Whether you're scheduling a wedding during the Easter season, planning academic calendars, coordinating family gatherings, or scheduling religious events, knowing future Easter dates can be extremely helpful. The algorithm is accurate for dates until the year 4099.
