Calculating Time Differences

You can calculate time differences using a formula in a spreadsheet.

This example shows the steps to calculate time differences in the same night.
  1. Enter the time 23:30 in A2 and press the Tab key. The cursor moves to B2.
  2. Enter the time 01:10 in B2 and press the Tab key. The cursor moves to C2.
  3. Enter the formula =(B2<A2)+B2-A2 in C2. The later time is B2 and the earlier time is A2. The result of the example is 01:40 or 1 hour and 40 minutes. In the formula, an entire 24-hour day has a value of 1 and one hour has a value of 1/24. The logical value in parentheses is 0 or 1, corresponding to 0 or 24 hours. The result returned by the formula is automatically issued in time format due to the sequence of the operands.
