Questions people ask
How do I convert 24 hour time to 12 hour?
For hours from 13 to 23, subtract 12 and add pm, so 15:30 is 3:30 pm. 00:00 is 12 am (midnight) and 12:00 is 12 pm (noon).
What does the step setting do?
It rounds results to a set interval. With a 15-minute step you only get times like 2:00, 2:15, 2:30 and 2:45.
Can the range cross midnight?
Set the range in order within one day for the cleanest results, such as 6 pm to 11:59 pm. Run a second range for times after midnight.
Is every minute in the range equally likely?
Yes, with any-minute steps each minute has the same chance. With bigger steps, each allowed time has the same chance.
