How to Calculate What Time Was it 15 Minutes Ago
Here are the steps to calculate what time it was 15 minutes ago:
Note the current time:
First, you need to know the current time. For example, let’s say it is 3:42 pm right now.
Subtract 15 minutes from the minute value:
Take the minute value of the current time (42) and subtract 15 from it. This gives you 27.
Adjust for going back an hour if needed:
If subtracting 15 minutes makes the minute value go below 0, then you need to subtract 1 from the hour value and use 60 + the negative minute value.
In this example, since 42 – 15 = 27, we don’t need to adjust the hour. The minute value 15 minutes ago was 27.
Write the previous hour and minute values:
Put together the hour value from the current time and the new minute value from Step 2 or 3. In this case, 15 minutes before 3:42 pm was 3:27 pm.
By following these four steps, you can calculate what time was it 15 minutes ago.
