I find Easter is Not mentioned in Scripture, just because Christian labels have been put on it does Not change it.Easter is Resurrection Sunday -- the day Christians remember what they believe to be Jesus' resurrection. Now, I you REALLY think that's secular, then I have nothing more to say to you.
Does Not change that Jesus wants to be remembered by his day of death - Luke 22:19
How can Resurrection Sunday always fall on a Sunday ______________
Just as Good Friday (Nisan 14 Jewish calendar ) or the Passover day can't always fall on a Friday.
It is a tradition outside of Scripture just taught as being Scripture.
