Today is Easter, which means the Easter Octave begins today. Octaves are feasts that last for 8 days. Nowadays there are only two: Christmas and Easter. Long ago when we took things far more seriously than we do today there were more. The Octave of Easter ends next Sunday, which is: Divine Mercy Sunday!!! You should start preparing because as Father Chris Alar says repeatedly in the videos I link to below, “Divine Mercy Sunday is better than a plenary indulgence!” (May not be an exact quote, but the point is the same.)
Why is Divine Mercy Sunday is better than a plenary indulgence? That’s because a plenary indulgence includes a requirement that you must have no attachment to sin in order to get the full remission of sins as well as the complete remission of temporal punishment due to sin. This is hard. If we have any attachment to sin, we only recieve a partial indulgence (complete remission of sins, but only a partial remission of the temporal punishment.) Divine Mercy Sunday is better, because you get the whole plenary remission of sins and temporal punishment WITHOUT ANY CONDITIONS! This is based on the promises Jesus made to St. Faustina as recorded in her Diary and made official when Divine Mercy Sunday and the promises were “canonized” by the Church when it was instituted and added to the liturgical calendar by Pope St. John Paul II in 2000. 
I’m repeating the following resources I posted last week:
The following are resources you can dive into so that you can learn about (or refresh your memory) Divine Mercy Sunday. I strongly recommend that you watch the YouTube videos; like, really, really set aside the time and watch them! (I think Fr. Chris Alar is the “Apostle of Divine Mercy Sunday!”)
I will quite likely remind you all again before the day. (See? I told you!)
