The Meaning of Easter

Easter, also called Resurrection Sunday, is the most important Christian celebration, commemorating the resurrection of Jesus Christ. Customs such as decorating eggs, blessing food, and re‑enacting the Way of the Cross are observed worldwide. However, the date of Easter is not fixed; it follows a lunar‑solar pattern established by early Church councils.

Core Calculation Rule

The rule for determining Easter Sunday was formalized at the First Council of Nicaea (AD 325). It depends on three fixed facts:

1. The Church fixes the spring equinox on March 21 each year (regardless of the astronomical moment).
2. It then finds the first full moon that occurs on or after that date – the Paschal full moon. This is an ecclesiastical full moon, not necessarily the astronomical one.
3. Easter Sunday is the first Sunday after this Paschal full moon.

These rules can be written concisely:

$\text{Paschal Full Moon} = \text{first full moon on or after } 21^{\text{st}} \text{ March}$

$\text{Easter Sunday} = \text{Sunday following the Paschal Full Moon}$

This algorithm, known as the computus, is implemented in the Easter calculator to handle any year in the Gregorian calendar.

Example: Easter in 2050

To see the rules in action, consider the year 2050:

• The Church’s equinox is set to March 21.
• The Paschal full moon is determined by the formula; the following Sunday becomes Easter.
• According to the computus, Easter Sunday 2050 falls on April 10.

The calculator performs these steps in an instant, saving you from manual calculation.

2023	April 6	April 9
2024	March 25	March 31
2025	April 13	April 20
2026	April 2	April 5
2027	March 22	March 28
2028	April 9	April 16
2029	March 30	April 1
2030	April 18	April 21
2031	April 7	April 13

When Can Easter Fall?

Because the Paschal full moon does not recur on a fixed Gregorian date, Easter Sunday can occur as early as March 22 and as late as April 25. For instance, in 2027 the full moon lands on March 22 (a very early date), making Easter fall on March 28. In contrast, 2030 sees a later full moon, pushing Easter to April 21. This variation explains why “when is Easter” changes from year to year.

Counting Down to Easter

Once you have the target date from the Easter date finder, you can calculate the remaining days using any standard date‑difference tool. The calculator itself gives you the precise Easter Sunday date, making the first step in any countdown effortless.
