March 29th doesn't appear in my calendar. Tried clearing cache, retarting phone, rebooting phone, factory reseting and reinstallin... Nope, 29th March isn't there. Will the world end on that day?
I think it's linked to daylight saving time and the change in clock time on that date - It should fix itself but if not try opening the calendar then tap the 3 dots and deselect show event for your time zone
