How to Calculate How Long Until 10 PM
You do not need a calculator. Three simple methods work for anyone.
Method 1: Subtract the Hours
This works best when your time is on a full hour.
- If it is 4 PM, then 10 minus 4 equals 6 hours.
- If it is 7 PM, then 10 minus 7 equals 3 hours.
- If it is 9 PM, you have 1 hour left.
Method 2: Count Up to the Next Hour
This trick is perfect when the clock shows minutes.
- Find how many minutes remain until the next hour.
- Add the full hours left after that.
Example: It is 5:40 PM. There are 20 minutes until 6 PM. From 6 PM to 10 PM is 4 hours. Total time left is 4 hours 20 minutes.
Method 3: Use the 24 Hour Clock
Convert your time and subtract from 22:00. If minutes are bigger than 00, borrow one hour and add 60 minutes.
Example: It is 3:45 PM, or 15:45. Subtract 15:45 from 22:00. You borrow one hour, so 21:60 minus 15:45 gives 6 hours 15 minutes.
