Roman historian Gaius Suetonius Tranquillus also wrote about Jesus and early Christians, whom he still referred to as Jews in 41 to 54 A.D. Ash Wednesday is always 46 days before Easter. It includes 40 fasting days, if the six Sundays, which are not days of fast, are excluded. The date of Easter is always the first Sunday after the full moon following a spring equinox. This year, Easter is on Sunday, April 16. Easter is considered the most important holiday on the Christian calendar. It is the day believed to be when Jesus Christ rose from the dead after being crucified. It follows Palm Sunday, which is April 9, Maundy Thursday, April 13, and Good Friday, April 14.
