A good timesheet does more than add hours. It should let you reconstruct the calculation: which day was worked, the start and end times, the break and how the final duration was obtained.
That is the difference between a table full of numbers and a record that can actually be checked.
Essential columns
For a simple monthly record, keep the date, start time, end time, break and worked duration. Add decimal hours, hourly rate, employee name, project or client reference when useful.
The Excel timesheet generator creates this structure for the selected month and year.
Use real Excel date and time values
A cell displaying “09:00” can contain either text or a true time value. They look similar but behave differently in formulas.
Excel stores time as a fraction of a day. Noon, for example, is 0.5. True time values can therefore be subtracted and formatted as durations.
Bethemesh generates usable date/time values rather than strings intended only for display.
Calculate a daily duration
For 09:00–17:00 with a 45-minute break, the span is eight hours and worked time is 7 h 15.
Our working-time guide covers split shifts and midnight crossings. When two intervals are used, keeping both source periods makes the result easier to audit.
Add decimal hours
Decimal hours are convenient when multiplying time by an hourly rate. 7 h 30 becomes 7.5 and 7 h 45 becomes 7.75.
In Excel, multiplying a time duration by 24 gives the corresponding decimal hours. Use the decimal hours converter for quick checks.
Estimate pay
At €18 per hour, 7.5 hours represent 7.5 × 18 = €135 in a simple calculation.
This does not reproduce every payroll rule. When some hours may be overtime, part-time additional hours, night work or Sunday/public-holiday work, identify them separately with the specialised calculators.
Add a summary sheet
A monthly workbook benefits from a summary showing the employee or project, period, total hours and estimated total pay when an hourly rate is supplied.
Bethemesh creates this summary alongside the detailed sheet so the headline figure remains traceable to the source rows.
Filters and frozen headers
Filtering helps isolate dates or rows. Freezing the header keeps column names visible while scrolling. Small usability features like these reduce errors in longer monthly files.
Should weekends be included?
A Monday-to-Friday template may omit weekends, while a seven-day operation needs them. The generator lets you choose.
Including a Sunday row does not determine how that Sunday is paid. See Sunday and public-holiday work for that separate question.
Check overtime week by week
A monthly total is useful for reporting but can hide weekly distribution. Under the ordinary French weekly model, overtime is counted week by week.
Keep dates so rows can be grouped by week and consult the overtime guide.
Part-time records
For part-time work, keep the contractual duration next to the time record. You can then compare the relevant period with the contract and identify possible additional hours.
See Part-time work: calculating additional hours.
Local processing and privacy
The Bethemesh generator builds the workbook locally in the browser from the entered information. That is useful for records that may contain a name, schedules or project reference.
As with any professional file, choose carefully where the workbook is stored and shared afterwards.
End-of-month checklist
Check missing days, midnight crossings, breaks that may have been deducted twice, a sample of daily durations, decimal-hour conversions and any hours that may fall under a special regime.
Key points
A useful timesheet preserves source data before producing totals. Dates, schedules and breaks should remain auditable. Decimal hours simplify calculations but do not replace the original times.
Use specialised tools to classify particular hours instead of trying to encode every employment rule into one spreadsheet formula.
