Understand why Sunday work, ordinary public holidays and 1 May do not follow one universal pay rule, and how to simulate premiums safely.
“Do I automatically get double pay for working on Sunday?” In France, the general answer is no. Sunday work does not carry one universal statutory salary premium across every sector. Compensation may come from a collective agreement, contract or a specific derogation scheme.
Public holidays also need to be separated from one another, with a particularly important special case: 1 May.
French official guidance does not impose the same automatic salary premium for every Sunday worker. The Sunday and public-holiday premium calculator therefore uses a configurable percentage.
The tool answers an arithmetic question: with a given number of hours, hourly rate and premium, what amount results? It does not decide that the premium is legally due.
For six Sunday hours at €15 per hour and an applicable +50% premium, base pay is 6 × 15 = €90. The premium is €45, producing €135 for those hours.
The calculation demonstrates the maths, not a universal right to +50%.
For French public holidays other than 1 May, applicable collective provisions can determine whether a premium or another benefit is due. “Public holiday” therefore does not automatically mean “double pay”.
Use the configurable scenario to reproduce the rate that actually applies.
French law gives 1 May a specific status. Where continuity of activity makes work necessary, an employee working that day receives, in addition to normal pay, compensation equal to that pay.
Arithmetically, this doubles the remuneration for the relevant hours. Do not extend this 1 May rule to every other public holiday.
An hour can fall on a Sunday that is also a public holiday, be overtime or occur during a night period. That does not prove all percentages should automatically be added.
The calculator offers a second optional premium so you can reproduce a combination when the applicable rules actually provide for it.
First determine whether the hour is overtime under the applicable counting period. Our overtime guide explains that step.
Then examine the Sunday rule separately. This avoids counting the same premium twice or stacking benefits that do not combine.
Use the same method for night work. First identify the hours inside the applicable night period with the night work premium calculator, then determine the compensation that applies.
See Night work: hours, premiums and compensatory measures.
When checking several Sundays or holidays, retain the actual dates and schedules before applying pay rules. The Excel timesheet generator provides that base record.
Keep three questions separate: how many hours were worked, what rule applies to the day concerned, and what premium or compensation that rule actually provides.
The calculator solves the arithmetic once the correct parameters are known. Sunday work is not universally premium-paid, and the special 1 May rule should not be generalised to every public holiday.
