Easter 2026: Why the Date Differs and When It Is Celebrated on April 5 and 12
Easter does not have a fixed date and shifts every year. In 2026, the difference is once again visible: some Christians will celebrate it on April 5, others on April 12. At first glance, this looks like a contradiction, but in reality, it reflects different calculation systems that developed historically and are still used in parallel.
Time for Action analyzed why this difference occurs and how exactly the date of one of the most important Christian holidays is determined.
Easter has no fixed date because its calculation is linked to both solar and lunar cycles. The main rule is the same across Christian traditions: the holiday falls on the first Sunday after the first full moon following the spring equinox. This principle is based on an ancient calculation system known as computus. It combines astronomical observations with calendar formulas that allow the date to be determined each year. However, the same rule does not guarantee the same result.
Why Different Dates Appear
The key reason for the difference lies in the use of different calendars and calculation methods. Western Christians, including the Roman Catholic Church and most Protestant communities, follow the Gregorian calendar. According to this system, Easter in 2026 falls on April 5. Orthodox Churches follow a different tradition. Even though some of them have adopted the Revised Julian calendar for fixed feasts, the calculation of Easter remains based on the older Paschal system linked to the Julian calendar. That is why Orthodox believers will celebrate Easter on April 12 in 2026. The difference arises not from a single factor, but from a combination of several:
- different determination of the spring equinox in calendar systems;
- different tables used to calculate the full moon;
- preservation of historical rules within the Orthodox tradition.
The transition of the Orthodox Church of Ukraine to the Revised Julian calendar applies to fixed dates, such as Christmas and other feasts with a constant date. Easter remains an exception. Its date is calculated according to a common system used by most Orthodox Churches, which has not changed after the calendar reform. Therefore, the transition to the new style did not affect the date of Pascha.
In some years, the dates of Easter in Western and Eastern traditions coincide. This happens when calculations based on different calendars lead to the same result. However, such coincidences are less frequent. In most cases, the difference is one or several weeks.
In 2026, the festive cycle looks as follows:
- Lazarus Saturday – April 4
- Palm Sunday – April 5
- Maundy Thursday – April 9
- Good Friday – April 10
- Holy Saturday – April 11
- Easter – April 12
- Bright Week – April 13–19
- Radonitsa – April 21
- Trinity – May 24
Great Lent in 2026 begins on February 23 and lasts until Easter. Different dates of celebration do not change the meaning of the holiday itself. Easter remains the central event of the Christian calendar regardless of when it is observed. The difference in dates is the result of historical development of church traditions, not a contradiction in faith or interpretation of the event. In 2026, these traditions are reflected once again in two dates April 5 and April 12. Both have clear explanations and are based on established systems of calculation.
