This work hours reference table shows the hours worked for a range of start time (24h, e.g. 9.5 = 9:30) values, assuming an end time (24h) of 17.5 and a break of 30 minutes. Every figure is computed with the same engine that powers our Work Hours Calculator, so the numbers are exact.

How to use this table

Find the row closest to your start time (24h, e.g. 9.5 = 9:30) and read across to the hours worked. For a value between two rows, the real figure sits between them — or enter your exact numbers in the Work Hours Calculator for a precise answer.
