Calendar Glitch On Iphone. Since the 15.1 update, the calendar app on my iphone frequently shows appointments on the wrong days, or with the wrong title, start/end time, etc. Another glitch affecting iphone alarms is causing chaos for people relying on the devices to get them up for critical work meetings, school and appointments.

I too got my calendar app to stop working and crashing upon opening it. Ensure calendar sync is enabled in the icloud menu, and your iphone is set to the correct date.
