Hours worked calculator Work hours calculator (hours and minutes to decimal)
In short
Hours worked = end − start − unpaid breaks. Do the math in minutes, add up the week, then convert the total to decimal hours: minutes ÷ 60.
15 minutes is 0.25 h, 30 minutes is 0.50 h and 45 minutes is 0.75 h. A shift that runs past midnight counts into the next day: 10 p.m. to 6 a.m. is 8 h.
Weekly hours calculator
Enter the start time, end time and unpaid break for each day. Leave days off blank. The total updates as you type.
Week total
- In hours and minutes
- 37 h 40 min
- In decimal hours
- 37.67
Total: 37 h 40 min, or 37.67 h in decimal. Days worked: 5.
Convert hours and minutes to decimal
For payroll or an hourly invoice, most software asks for decimal hours. The conversion works both ways.
Examples: 7:45, 7 h 45, 45 min, 37:30.
Examples: 7.75 or 7,75.
The math happens in your browser: the hours you enter are not sent anywhere and are not kept.
Examples
| Start | End | Unpaid break | Hours and minutes | Decimal hours |
|---|---|---|---|---|
| 7:00 | 15:30 | 30 min | 8 h | 8.00 |
| 6:45 | 15:10 | 30 min | 7 h 55 min | 7.92 |
| 8:15 | 17:00 | 45 min | 8 h | 8.00 |
| 22:00 | 6:00 | 30 min | 7 h 30 min | 7.50 |
| 7:00 | 12:00 | 0 min | 5 h | 5.00 |
Calculated by the calculator on this page. The fourth day runs past midnight.
Table: minutes to decimal hours
Divide the minutes by 60 and round to the hundredth. The values people look up most:
| Minutes | Decimal hours |
|---|---|
| 5 min | 0.08 |
| 10 min | 0.17 |
| 15 min | 0.25 |
| 20 min | 0.33 |
| 25 min | 0.42 |
| 30 min | 0.50 |
| 35 min | 0.58 |
| 40 min | 0.67 |
| 45 min | 0.75 |
| 50 min | 0.83 |
| 55 min | 0.92 |
| 60 min | 1.00 |
Rounded to the hundredth of an hour. One minute is about 0.0167 h.
How to calculate hours worked
- For each day, subtract the start time from the end time. From 7:00 to 15:30, that is 8 h 30 min.
- Take off unpaid breaks. With a 30-minute meal break, 8 h remain.
- Add up the days in hours and minutes, not in decimals that were already rounded.
- Convert the week total: minutes ÷ 60. 37 h 40 min gives 37 + 40 ÷ 60 = 37.67 h.
Which breaks to take off?
- According to the CNESST, breaks granted by the employer are paid: they count as hours worked. Do not take them off.
- The 30-minute meal break, granted after 5 consecutive hours of work, is unpaid, unless the person must stay at their workstation. That is usually the one you take off.
- A collective agreement or a decree may provide otherwise for the meal period (Act respecting labour standards, s. 79).
- In construction, an employee governed by Act R-20 is not covered by these rules of the Act respecting labour standards (s. 3): the collective agreement of their sector applies instead.
A shift that runs past midnight
If the end time is earlier than the start time, the shift ended the next day: add 24 h to the end time. From 22:00 to 6:00: (6 + 24) − 22 = 8 h. The calculator does it on its own and flags it as "past midnight".
Why add up before converting
Decimal hours are often rounded. Three 10-minute periods give 0.17 + 0.17 + 0.17 = 0.51 h if you round each one, while 30 minutes is exactly 0.50 h. The calculator adds up the minutes, then converts the total.

Divide the minutes by 60. 15 minutes = 0.25 h, 30 minutes = 0.50 h, 45 minutes = 0.75 h, 20 minutes = 0.33 h. For 7 h 45 min: 7 + 45 ÷ 60 = 7.75 h.
Add 24 hours to the end time before subtracting the start time. From 23:00 to 7:00: (7 + 24) − 23 = 8 h. The calculator does it on its own.
Only unpaid breaks. According to the CNESST, breaks granted by the employer are paid and count as hours worked. The 30-minute meal break after 5 consecutive hours is unpaid, unless the person must stay at their workstation. In construction, an employee governed by Act R-20 follows the collective agreement of their sector instead.
8 h 20 min = 8 + 20 ÷ 60 = 8.33 h, rounded to the hundredth. The other way, 8.33 h × 60 gives about 500 minutes, or 8 h 20 min.
