How Daily Working Hours Are Calculated sounds like a simple question, but in the UAE the answer has a few layers: what counts as a “working hour,” what does not, and how breaks, prayer time, and Ramadan reductions change the number at the end of the day. Whether you are checking your payslip, filling in a timesheet, or just making sure your employer is counting fairly, this guide walks through the calculation step by step.
The calculation always starts from the same base: the UAE Labour Law (Federal Decree-Law No. 33 of 2021) caps a standard working day at 8 hours. Everything else — breaks that get subtracted, overtime that gets added, and the Ramadan reduction — is built on top of that number. For a full picture of the rules behind the maths, see our companion piece, Working Hours Rules Explained.
Quick Answer
Your daily working hours = time from start of duty to end of duty minus rest breaks for meals and prayer. Breaks are not counted as working time. The result is compared against the daily maximum (8 hours normally, 6 in Ramadan); anything above it is overtime. So a 9:00 am–6:00 pm shift with a 1-hour lunch = 8 working hours.
How Daily Working Hours Are Calculated: The Basic Formula
The calculation has three steps:
- Take the full duty period: the time from when you start work to when you finish (including any mandatory presence on site).
- Subtract rest breaks: time for lunch, prayer, and rest is excluded. The standard expectation is at least 1 hour of break time after every 5 consecutive working hours, but your actual scheduled break is what gets subtracted.
- Compare the result to the daily maximum: 8 hours on a normal day, 6 hours during Ramadan. Anything above the maximum is overtime (at the appropriate premium rate); anything below is simply your normal day.
In formula form:
Daily working hours = (end time − start time) − rest breaks
This is the number your employment contract and your payslip should be consistent with. If your payslip says 8 hours but your timesheet shows 8 plus an unpaid lunch hour, that is normal — the lunch hour was subtracted before the count was made.
What Counts and What Does Not
The single biggest source of confusion is what goes into the duty period. As a general guide:
| Activity | Counts as working time? |
|---|---|
| Time at your desk / workstation performing duties | Yes |
| Mandatory meetings, training, briefings | Yes |
| On-site standby time required by your employer | Usually yes |
| Lunch / meal breaks | No |
| Prayer breaks during the day | No |
| Commuting to and from work | No |
| Off-duty time at home (even for on-call roles, until actually called) | Usually no |
The details vary by role and company policy — for a deeper look at grey areas like travel between sites and waiting time, see our guide on what counts as working time.
Worked Examples
Example 1: Standard office day
- Duty period: 9:00 am – 6:00 pm = 9 hours
- Lunch break: 1 hour
- Daily working hours: 9 − 1 = 8 hours (at the standard maximum — no overtime)
Example 2: Day with a prayer and lunch break
- Duty period: 8:00 am – 5:30 pm = 9.5 hours
- Lunch (45 minutes) + prayer break (30 minutes) = 1.25 hours
- Daily working hours: 9.5 − 1.25 = 8.25 hours (0.25 hours = 15 minutes of overtime)
Example 3: Ramadan day
- Duty period: 9:00 am – 3:00 pm = 6 hours
- Break: none scheduled (short day)
- Daily working hours: 6 hours (at the Ramadan maximum — no overtime)
Example 4: Long shift day
- Duty period: 8:00 am – 8:00 pm = 12 hours
- Lunch (1 hour) + two short breaks (30 minutes) = 1.5 hours
- Daily working hours: 12 − 1.5 = 10.5 hours (2.5 hours of overtime at the standard premium)
Ramadan: When the Daily Maximum Changes
During Ramadan, the daily maximum drops from 8 hours to 6 hours for all private-sector employees. The formula itself does not change — you still subtract breaks from the duty period — but the comparison point is lower. This matters for overtime: if you work 8 hours on a Ramadan day (after breaks), 2 of those hours are overtime, even though 8 hours would be a normal day the rest of the year.
Many employers also simplify by removing scheduled breaks during Ramadan and running a straight 6-hour day. Either way, the rule to check is simple: working hours (after breaks) − 6 = overtime hours during Ramadan.
Daily vs Weekly Calculation
The labour law caps both the day (8 hours) and the week (48 hours), and the two interact. A few points to keep straight:
- Overtime is normally triggered by the daily limit — one long day of 10 hours creates 2 hours of overtime even if the rest of the week is light.
- The weekly cap of 48 hours is a separate ceiling. In a 5-day week of 8-hour days you are at 40 hours, well under it; in a 6-day week of 8-hour days you hit exactly 48.
- Your weekly rest day (at least one paid day off per week) is not part of either calculation — if you are required to work it, the extra day is compensated separately, either with a substitute day off or overtime-rate pay.
For the full weekly breakdown, see our guide on weekly working hours explained. The official UAE Government Portal also summarises these daily and weekly limits in its employment guidance.
Remote and Flexible Workers
The formula is the same for remote workers, but applying it is trickier because nobody is watching you clock in. In practice:
- Many remote contracts define a fixed daily schedule (e.g. 9:00 am – 5:00 pm with a 1-hour break), and the calculation follows that schedule.
- Time-tracking tools used by some companies measure active work time, but the legal concept is still duty period minus breaks — not minutes your mouse moved.
- If you work flexible hours, agree in writing with your employer how the daily count is made, so there are no surprises on the payslip.
Whatever your arrangement, keeping your own daily record is the best protection. Our guide on how to keep track of working hours shows simple methods that take under two minutes a day.
Common Mistakes in Daily Calculations
- Counting breaks as working time: lunch and prayer breaks come off the total. If your HR system adds them in, your “hours worked” will look higher than the legal count.
- Forgetting the Ramadan change: using 8 hours as the overtime threshold during Ramadan understates your overtime.
- Mixing up basic wage and total salary: overtime premiums are calculated on the basic wage only, not allowances. The hours are the same either way, but the pay figure changes.
- Ignoring partial hours: 15 or 30 minutes of overtime still counts — small amounts add up over a month.
- Assuming travel time counts: your normal commute does not count as working time, so a long drive to the office does not add to the daily figure.

Frequently Asked Questions (FAQs)
How are daily working hours calculated in the UAE?
Subtract rest breaks (meals, prayer) from your full duty period (start time to end time). The result is your daily working hours, capped at 8 hours normally and 6 hours during Ramadan; anything above is overtime.
Do lunch breaks count in daily working hours?
No. Meal and prayer breaks are excluded from the working-hours count. They do not reduce your salary either — they are simply not part of the 8-hour day.
Is the daily limit 8 hours including breaks?
No — the 8-hour limit applies to working time after breaks are excluded. A 9:00 am–6:00 pm day with a 1-hour lunch equals exactly 8 working hours.
How do you calculate overtime for a single day?
Daily working hours (after breaks) minus the daily maximum (8 normally, 6 in Ramadan) = overtime hours. Multiply by your basic hourly wage plus the premium (25% standard, 50% for night hours).
Does prayer time count as working hours in the UAE?
No. Prayer breaks are part of the rest period and are excluded from working time, like meal breaks.
Does commuting time count towards daily working hours?
No. Travel to and from your normal workplace is not counted as working time under standard arrangements.
The Bottom Line
Calculating daily working hours in the UAE comes down to one subtraction: your full duty period minus your breaks. Compare the result to 8 hours (6 in Ramadan) and you know exactly where you stand — normal day or overtime. Run the numbers for a typical week, keep your own simple log, and compare it against your payslip each month. If the figures do not match, raise it with HR in writing; if it is not resolved, the Ministry of Human Resources and Emiratisation (MOHRE) is the official channel for guidance. For anything affecting pay or contract terms, always verify current details on official government portals.
