That's a common mis-conception.
1) Pascha ≠ Easter
2) Easter = Ishtar, "The Queen of Heaven" who is a Sumerian / Babylonian goddess (which the Roman Catholic church adopted)
3) Easter is not commanded in the Bible (not mentioned in the New Testament)
This is thoroughly covered by Alexander Hislop's, The Two Babylons (1853), which is essential reading for a Christian has wondered about the authenticity of Christ-mas, Easter, and the like

It was also mandated to be on "Sunday" which is NOT a sabbath day, not the 7th day, meaning it is totally out of sync with God's 4th commandment / sabbath (shabbat) / passover (pesach) / (the real) pascha.

passover.
Matthew writes, "Now the first day of
the feast of unleavened bread the disciples came to Jesus, saying unto him, Where wilt thou that we prepare for thee to
eat the passover (πάσχα, pascha)? And he (Jesus) said... My time is at hand;
I will keep the passover at thy house with my disciples. ... And the disciples did as Jesus had appointed them; and
they made ready the passover." (Matthew 26:17-19)
https://www.biblegateway.com/passage/?search=Matthew+26%3A1-19&version=KJV;TR1550i.e. "The Feast of Unleavened Bread" = Passover (Pesach) = Pascha
≠ Easter. Easter is pagan idolatry.
