How to Calculate What Time Was It 15 Minutes Ago
Figuring out what time was it 15 minutes ago is a simple math calculation. By following these easy steps, you can quickly determine that past time:
Note the current time:
First, you need to know the present time. Look at a clock, your phone, or any timepiece that shows the accurate current hour and minutes.
Subtract 15 minutes from the current minutes:
Take the number of minutes shown in the current time, and subtract 15 from it. For example, if it's 3:28 PM now, subtract 15 from 28 to get 13.
Carryover if needed:
If subtracting 15 from the current minutes makes the new minute value negative, carry over by subtracting 1 from the current hour and adding 60 to the new minute value. So if the time was 2:02 PM, 2 minus 15 is -13, so the hour becomes 1 and the minutes become 47 (60 - 13).
Adjust the hour if required:
After carrying over if needed, the new hour reflects what it was 15 minutes ago. Continuing the example above of the present time being 2:02 PM, 15 minutes earlier was 1:47 PM.
