Yes, Easter was a number of days ago. And, yet, Easter — the Resurrection of Our Lord and Savior — is too big an event to be encompassed in a single day. All week long, during Mass, we recite or sing the Gloria, even on weekdays, because we are still celebrating Easter.
Easter week concludes with the Octave this coming Sunday, April 11. But, even then, Easter does not end. We celebrate Easter for an entire week of weeks, or seven weeks, which takes us to late May.
On Sunday, May 23, we celebrate Pentecost Sunday. Only then, on Monday, May 24, do we return to Ordinary Time.
So let our Easter celebration truly last for the entire 50 days!
How wonderful that the Easter Season is even longer than Lent!
