Opinion on the holidays or on moving your graduation dates?

We are not obligated to observe any OT feasts - and Easter is not one (though many believe that Easter is the fulfillment of Passover and the feast of First Fruits). I believe in using this time when much of the world is religious and actually open to hearing about Jesus dying and rising again. Let's forget getting caught up in pagan festivities and use every opportunity to get the Gospel out. Let's redeem this time while many are open to the truth to get it to them.
