How Easter Date Is Determined
Easter is a moveable feast whose date is computed using ecclesiastical rules rather than the astronomical full moon in all traditions. The modern formula aims to track the March equinox and the first subsequent full moon.
Computation Rules
- March 21 is treated as the canonical vernal equinox.
- Easter is the first Sunday after the first full moon occurring on or after March 21.
- If the full moon falls on a Sunday, Easter is observed the following Sunday, unless special rules apply in some Orthodox traditions using the Julian calendar.
2017 Easter Calendar Context
Using the computus rules above, the first full moon on or after March 21 in 2017 occurred on March 25. The next Sunday following that full moon was April 16, establishing the observed date.
