This calculator counts the hours between two timestamps that fall within your defined work schedule. It's more precise than counting business days because it accounts for partial days at the start and end of the range.
For example, if you enter Monday 10 AM to Wednesday 3 PM with a 9–5 work schedule, the result is: 7 hours Monday + 8 hours Tuesday + 6 hours Wednesday = 21 working hours.

|---|---|---|---|
| Mon 10:00 AM | Mon 5:00 PM | 9–5 | 7 hours |
| Mon 9:00 AM | Fri 5:00 PM | 9–5, M–F | 40 hours |
| Mon 9:00 AM | Wed 3:00 PM | 9–5, M–F | 27 hours |
| Fri 3:00 PM | Mon 10:00 AM | 9–5, M–F | 2 hours (Fri only) |
