Unlocking The Mystery Behind Easter's Date . . .

Does Easter seem early this year?
It does to some of us.
So, how is the date for Easter determined?

Easter is calculated via the Easter dating method devised by Pope Gregory XIII and his astronomers and mathematicians.
According to the Gregorian calendar Easter is always one of the 35 dates between March 22 and April 25. The canonical rule is that Easter Day is the first Sunday after the 14th day of the lunar month (the nominal full moon) that falls on or after March 21 (nominally the day of the vernal equinox). So, this year Easter comes 11 days after the beginning of spring.
Next year Easter will fall on April 21 which is later than normal but seems more appealing. And in 2020 (the magical Year of Perfect Vision) Easter will fall on April 12, which seems about right.
One would expect that it would be a relatively chilly Easter this year -- in fact, here in the Philadelphia region they're calling for wet snow. UGH! And the week leading up to Easter has  still been a bit cooler than normal.
But we actually remember balmy Easters in March and chilly Easters in April.
Why is the date of Christmas fixed while the date of Easter changes each year? 
That's a question for another time.
