Make Calendar Times Specific
The iOS Calendar is a handy way to keep track of your events, appointments and meetings, as well as add time-based reminders and notes. But, for some reason, Calendar seemingly only lets you set the time by hours and five minute increments. Well, you can be more specific, but Apple just didn’t let us know..
There’s actually an extremely well-hidden way to change the time increments. When creating a calendar entry, just double tap the time when creating a calendar entry.
It’s easy-to-miss, but you should now see the minute section change to single minutes, rather than five-minute intervals.
