Easter season

I've heard twice today the idea that Easter is a season, not a Sunday.  While I understand that based on the liturgical calendar, I wonder what that means in practice.

The Easter season -- what does that mean for us?  What happens after the resurrection?  The disciples are locked in a room, fearing life without Jesus.  Thomas, who can't stand it all anymore, leaves.  The Easter season has uncertainty and loneliness.  Do we experience that?

In the Easter season, Peter has to live with his betrayal of Jesus.  He learns about forgiveness on the shore of a lake, over a campfire.  Do we experience that?

In the Easter season, the disciples witness the ascension of Christ.  A miracle.  Do we experience that?

What is part of our Easter season?
