No I have not gotten my calender confused. Many may not know that the Eastern Orthodox celebrate their Holy Days using a different calender.
So this Sunday will be Easter for them. So to all of those having Easter tomorrow

Christ is risen! Indeed, He is risen!

Wishing peace and blessings upon all Eastern Rite Christians during this
Feast of Pascha. Please join me in the Christ is Risen Prayer from the
Byzantine Tradition (traditionally recited from Easter Sunday until the
Wednesday before Ascension Thursday):

*Christ is risen from the dead! By death He conquered Death and to those
In the graves, He granted life!*

Amen and Alleluia!
