Easter, Lunar New Year and Eid: Why These Holidays Move Every Year

Easter Sunday can land anywhere between 22 March and 25 April. That five-week swing is not random. It is locked to the Moon.

Western Easter is fixed to the first Sunday after the ecclesiastical full moon that falls on or after 21 March. The church does not use the astronomical full moon directly. It uses a set of tables that define the ecclesiastical full moon, which keeps the date tied to an ancient rhythm rather than precise lunar observation. The rule sounds simple, but it pushes the holiday across a wide window. One year you are hunting eggs in late March. The next you are doing it in mid-April.

The specific dates for the coming years show the range. Western Easter falls on 5 April 2026, then jumps earlier to 28 March 2027, then slides back to 16 April 2028. Check a public holidays calendar for any given year and you will see Easter anchoring a long weekend that moves with it.

Why Orthodox Easter is often later

Orthodox churches calculate Easter using the same formula, but they apply it to the older Julian calendar. That calendar now runs 13 days behind the Gregorian calendar most of the world uses. The result is an Orthodox Easter that usually lands after the Western date. In 2026, Western Easter is 5 April while Orthodox Easter arrives on 12 April. The gap widens dramatically in 2027: 28 March for Western churches, and a full 2 May for Orthodox Christians. Then in 2028 the two align. Both observe Easter on 16 April. That rare convergence happens when the Julian and Gregorian full moons point to the same Sunday. If you are tracking the countdown, a dedicated Easter countdown will show the days remaining to the Western date.

Lunar New Year: a moon between two fixed points

Lunar New Year usually starts on the second new moon after the winter solstice. In practice, that puts the date somewhere between 21 January and 20 February. The holiday begins a new year on the traditional lunisolar calendar, which keeps months tied to moon phases while adding leap months to stay roughly aligned with the seasons.

The dates for the next three years run across the permitted range. In 2026, Lunar New Year falls on 17 February, near the late edge. 2027 brings it forward to 6 February. 2028 pushes it even earlier, to 26 January, just five days after the earliest possible date. That shift from mid-February to late January in two years shows how the lunisolar rhythm compresses and stretches against the Gregorian calendar. A Lunar New Year countdown ticks toward that new moon moment.

Eid al-Fitr: the pure lunar drift

Eid al-Fitr marks the end of Ramadan, the fasting month in the Islamic calendar. That calendar is purely lunar. Twelve lunar months make a year of about 354 days. That is roughly 11 days shorter than the 365-day solar year. The shortfall is not corrected with leap months. So Eid steps backward through the Gregorian calendar by about 11 days each year. Over roughly 33 years it cycles through every season.

That drift is why Eid falls in spring now and will move into winter within a few years, then autumn, then summer. The estimated dates for the coming years trace the slide clearly. In 2026, Eid al-Fitr is expected around 20 March. In 2027, it shifts to around 9 or 10 March. By 2028, it lands around 26 February. These dates remain estimates until the new crescent moon is actually sighted. The Islamic calendar hinges on that physical observation. Cloud cover or atmospheric conditions can delay the announcement by a day, and different countries can start Eid on different days based on local sightings. Public holiday calendars, including lists of holidays in Indonesia, often print Eid dates as provisional until the official confirmation comes.

Dates at a glance, 2026 to 2028

| Holiday | 2026 | 2027 | 2028 | |---|---|---|---| | Western Easter | 5 April | 28 March | 16 April | | Orthodox Easter | 12 April | 2 May | 16 April | | Lunar New Year | 17 February | 6 February | 26 January | | Eid al-Fitr (estimated) | ~20 March | ~9–10 March | ~26 February |

Side by side, the patterns differ. Western Easter jumps around within its late-March-to-late-April box. Orthodox Easter tracks it loosely, then syncs up. Lunar New Year bounces between late January and mid-February. Eid marches steadily backward, about 11 days each year.

Planning around moving holidays

These shifts matter for anyone booking travel, scheduling family gatherings, or managing work across countries. A holiday that fell in April last year might land in March next year. Eid moves enough each year that a fixed annual leave policy will miss it more often than it hits. Lunar New Year can flip a quiet late January into a peak travel period. Easter’s date drags school holidays and bank holidays with it, so the spring calendar reshapes itself annually.

If you need a precise day count for Easter, a tool like how many days until Easter gives the number directly. For Eid, the official announcement from religious authorities is the only certain date. Everything before that is a projection. The rules behind these holidays never change. Their dates on a modern calendar always will.
