Easter is not Christian; though it is mentioned in Acts 12, most authorities consider it a translation error. Passover is God-ordained and mentioned 70 times in the scriptures first in Exodus.
Easter was a pagan holiday to the sun or fertility goddess (many names) in ancient times.
Constantine, of the then Roman Christian church-state, had a hand at the Council of Nicaea, c ~ 325 AD or so to change the time of remembrance of Christ’s death and resurrection to Easter instead of Passover.
Another example of one of the “traditions of men” people follow rather than what God ordained.
Nevertheless, yes, to God be the glory, Christ is rise!
