A gem from Luther:

We have Easter as often as we celebrate the Mass, preach, and administer the holy Sacrament. With us Christians every day is Easter, except that for ancient memory’s sake we observe a special Easter once a year. And that is not wrong but good and laudable, to observe the time when Christ died and rose again, even though our remembrance of His suffering and resurrection is not restricted to such a time but may be done on any day. As He says: “As often as you do this, do it in remembrance of Me” (1 Cor. 11:25).
