How to Calculate Split Shift Hours
A split shift is a working day in two parts with a long gap between them — a breakfast and dinner service, a morning and evening bus run, early and late home-care visits. Counting the hours means either adding the two parts or treating the gap like a long break. This guide shows both, including a split shift that finishes after midnight.

What counts as a split shift
The usual idea is a gap longer than an ordinary meal or rest break, so that the day is really two blocks of work. Whether the gap is paid, and whether a split shift earns anything extra, depends on the employer’s arrangement and the rules where you work.
Add the two parts
- First part: 7:00 AM to 11:00 AM is 4 hours.
- Second part: 4:00 PM to 8:30 PM is 4 hours 30 minutes.
- Total: 8 hours 30 minutes, or 8.5 decimal hours.
One span minus the gap
The same day can be measured from first start to last finish — 7:00 AM to 8:30 PM is 13 hours 30 minutes — with the 5-hour gap from 11:00 AM to 4:00 PM taken off like a break: 13 hours 30 minutes − 5 hours = 8 hours 30 minutes. In the Shift Length Calculator With Breaks, enter the gap as a 300-minute break.
A split shift that ends after midnight
From 6:00 PM to 10:00 PM, then 11:30 PM to 2:00 AM: the parts are 4 hours and 2 hours 30 minutes, 6 hours 30 minutes in all. As one span, 6:00 PM to 2:00 AM is 8 hours, minus the 90-minute gap, which gives the same 6 hours 30 minutes.
More examples
| First part | Second part | Gap | Hours worked |
|---|---|---|---|
| 7:00 AM – 11:00 AM | 4:00 PM – 8:30 PM | 5 hours | 8 hours 30 minutes |
| 6:00 AM – 9:30 AM | 2:30 PM – 7:00 PM | 5 hours | 8 hours |
| 10:00 AM – 2:00 PM | 5:00 PM – 9:00 PM | 3 hours | 8 hours |
| 6:00 PM – 10:00 PM | 11:30 PM – 2:00 AM | 1 hour 30 minutes | 6 hours 30 minutes |
The spread of the day
The time from the first start to the last finish — 13 hours 30 minutes in the first example — is sometimes called the spread or span of the day. Some agreements refer to it separately from hours worked, so it is worth keeping both numbers.
Split Shift Hours FAQ
- How do I calculate hours for a split shift?
- Work out each part separately and add them, or measure from first start to last finish and subtract the gap.
- Does the gap in a split shift count as hours worked?
- That depends on your employer’s arrangement and the rules where you work. The arithmetic leaves it out unless you choose to count it.
- How do I enter a split shift in a shift length calculator?
- Use the first start and last finish as the shift, and enter the gap between the parts as a break.
- What if the second part of a split shift ends after midnight?
- Add 24 hours to the finish time when measuring that part, or the whole span. 11:30 PM to 2:00 AM is 2 hours 30 minutes.
- What is the spread of a split shift?
- The time from the first start to the last finish, including the gap — usually longer than the hours worked.
