Ever tried to plan a family brunch months in advance and realized you have absolutely no clue when the holiday actually falls? It’s frustrating. One year it’s in March, and the next, you’re looking at late April. You aren't alone in your confusion.
Determining what days is easter on isn't as simple as checking a fixed date like Christmas or Halloween. It feels like a moving target because, well, it literally is. Most people think it’s just a random Sunday chosen by the church, but there is actually a heavy dose of ancient astronomy and complex mathematics involved in that final date on your kitchen calendar.
The Moon Rules Everything
To understand the scheduling, you have to look up. Way up.

Basically, the date is tied to the Paschal Full Moon. This isn't just any moon; it’s the first full moon occurring on or after the spring equinox. If that full moon hits on a Sunday, Easter is bumped to the following Sunday to ensure it doesn't overlap with Passover. This rule was established way back in 325 AD at the Council of Nicaea. The bishops wanted a unified date for all Christians, but they accidentally created a system that confuses everyone 1,700 years later.
Because the lunar cycle is about 29.5 days and our solar year is 365 days, the two never perfectly align. This "drifting" is why you see such a wide range of possible dates. Easter can happen as early as March 22 or as late as April 25. Honestly, it’s a massive window. If you’re born on March 25, you might have an Easter birthday once or twice in your life, or maybe never.
The math used to calculate this is called the "computus." It was a huge deal for medieval scholars like the Venerable Bede. They spent their lives trying to reconcile the lunar and solar calendars so people would know when to stop eating meat for Lent. Today, we just use Google, but the underlying logic remains a relic of a time when the stars were our only clock.
Upcoming Dates: Marking Your Calendar Through 2030
If you're trying to figure out what days is easter on for the next few years, the dates are already locked in by the Vatican and astronomical tables.
For 2026, Easter falls on April 5. It’s a relatively "early-mid" date. If you look at 2027, it jumps to March 28. Then, in 2028, it’s back into April on the 16th. 2029 sees it on April 1, and in 2030, it lands on April 21.

The variation affects everything. Think about the flower industry. When Easter is in March, lily growers have to use heat to force blooms early. When it’s in late April, they’re fighting to keep the flowers from wilting before the big day. It's a logistical nightmare for retailers, too. A "late Easter" usually means better sales for spring clothing because the weather is actually warm enough for people to wear those pastel dresses and linen suits.
The Great Divide: Why Orthodox Easter is Different
This is where it gets even more complicated. You might have a neighbor who celebrates Easter a week or even a month after you do.
The Western church (Catholic and Protestant) uses the Gregorian calendar, which is what we use for our daily lives. However, many Orthodox churches still follow the Julian calendar for religious festivals. They also stick more strictly to the rule that Easter must come after Passover. Because the Julian calendar is currently 13 days behind the Gregorian one, their "equinox" hits later.
In 2025, a rare thing happens: both East and West will celebrate on the same day, April 20. It's a brief moment of calendar harmony. But by 2026, they diverge again, with Orthodox Easter falling on April 12 while Western Easter is on April 5.
It’s sorta wild that a calendar change from the 1500s still dictates when people go to church today.

In the 1920s, the UK actually passed the Easter Act of 1928. This law sought to fix Easter to the first Sunday after the second Saturday in April. If it had worked, Easter would always be between April 9 and April 15. The law is technically still on the books, but it was written with a "trigger" clause: it only goes into effect if all the major Christian churches agree.
They haven't.
Pope Francis and various Coptic and Orthodox leaders have occasionally mentioned wanting a fixed date to make life easier for modern families. Imagine a world where school spring breaks and public holidays actually lined up every year. But tradition is a powerful thing. For now, we are stuck with the moon.
How to Plan When the Date is Moving
Since the holiday moves, your preparation has to move with it.
If Easter is in March, you're likely dealing with mud, coats, and indoor egg hunts. If it’s late April, you’re looking at a full-blown garden party. This "drift" changes the vibe of the holiday entirely. A March Easter feels like the very end of winter, a desperate grab for spring. An April Easter feels like the peak of the season.
When you're trying to figure out what days is easter on, don't just look for the Sunday. Remember that Ash Wednesday and Mardi Gras move right along with it. The entire liturgical season is on a bungee cord tied to that first full moon after the equinox.
Actionable Steps for the Next Few Years
- Check the full moon: If you see a full moon in late March, know that Easter is likely the following Sunday. This is a quick way to "eye-ball" the date without a calendar.
- Coordinate your vacation: If you work in a field where you get "Good Friday" or "Easter Monday" off, check the dates through 2030 now. A late April Easter is a much better time for a Caribbean getaway than a chilly March one.
- Book reservations early: For the 2026 date (April 5), restaurants will likely be packed because it’s a "comfortable" spring date. If you’re planning a large family gathering, you should be looking at venues at least four months out.
- Watch the overlap: In years where Western and Orthodox Easter align (like 2025), expect travel prices to spike significantly, especially in Europe and the Middle East, as twice as many people are traveling for the same holiday.
Understanding the cycle won't make the date stay put, but it at least explains why you’re always searching for it. The moon dictates the ham, the eggs, and the church bells. It’s been that way for nearly two millennia, and despite our high-tech world, the old ways aren't changing anytime soon.
