Easter is the most important holiday on the Christian calendar. It coincides with Passover and occurs each year on the first Sunday following the first full moon after the vernal equinox.  Therefore, Easter could happen on any given Sunday between March 22 and April 25 depending on the year.

The 40 days prior to Easter are called Lent. It’s a 40-day period layered with Biblical and historical significance. Forty days was how long Noah dealt with rain on the ark; 40 days was how long Moses was on the mountaintop; it was 40 days repentance given to Nineveh by Jonah; and perhaps the most well-known, it was 40 days in which the devil tempted Jesus as he prayed in the desert.
