Most traditional grocery stores on Long Island are expected to remain open on Easter Sunday, although some big-box and warehouse stores will also be closed. The date of Easter Sunday varies due to the nature of the event and the timing of the vernal equinox, which occurs from March 19-21. CVS and Walgreens pharmacies are open, but expect shorter hours and reduced staffing. Other notable stores include DSW, IKEA, and Ulta Beauty.
