Expected Behavior

Current Behavior

Steps to Reproduce

1. Create event with minute that isn't divisible by 15 (eg 7:50am)

2. Look at calendar

3. Notice: doesn't render

Possible Solution (Not obligatory)

Allow shorter time intervals (5 min?)

Context

I think 5 min interval would be better, as totally arbitrary intervals are not that popular and implementing them might be significantly more difficult than a 5 min interval.
