Why does Easter fall on different Sundays?
Easter moves around each year because its date isn’t fixed to the regular calendar—it’s based on a mix of solar and lunar cycles.
Here’s the key idea:
- Easter is celebrated on the first Sunday after the first full moon following the spring equinox.
- The spring equinox is fixed (around March 21).
- The full moon date changes every year because it follows the Moon’s cycle (~29.5 days).
- Then Easter is set to the following Sunday.
What this means in practice:
- Easter can fall anywhere between March 22 and April 25.
- If the full moon is just after March 21 and lands on a Saturday, Easter is the very next day (early date).
- If the full moon is late in April, Easter shifts later.

That combination of astronomy + tradition is why the date changes every year.
