It may seem like Easter is recently this yr , but according to the lunar calendar , it ’s the right way on prison term .
Easter Sunday is cognize as a " moveable fiesta , " because it does not hap on a specific date each year . Instead , the Christian vacation is celebrate on the Sunday after the first full synodic month that occurs on or the day after thespring equinox(March 20 in 2017 ) . This year , the full moon peaked on April 11 , designating the follow Sunday ( April 16 ) as Easter .
This calculation for the celebration ’s date was determined by a great council of Christian church , call the First Council of Nicaea , in the year 325,reported Space.com . At that meter , the importance of the Easter celebration brought thousands of Christians to Jerusalem and other shrines to observe the holiday .

However , the calculation is not exact , particularly because calendar have changed . When the council typeset its calculation for the Easter holiday , the rules remark a fixeddate for the fountain equinoxas March 21 . But from 2004 through 2103 , the equinoctial point will occur no later than March 20 . Therefore , the astronomical dating of Easter can dissent from that of the church building .
One of the more remarkable contradictions of this dating will be Easter in the twelvemonth 2038 , according to Space.com . Astronomically , Easter should devolve on March 28 that class , because the equinox falls on March 20 and the full moon fall out the next day . However , due to the church building ’s rules , Easter will be observed on April 25 , its former possible date give the lunar cycle ’s length of about a month .
So , while Easter may feel " late " this year , the 2038 solemnisation will take post even later .
