Add business days to date
A ten-working-day deadline set on a Monday falls on the Friday of the following week — fourteen calendar days later, not ten. That four-day gap is why "ten working days" and "two weeks" are used interchangeably in practice, and why a period quoted in working days always takes longer than it sounds.
Weekends are skipped but public holidays are not, because they differ by country and region. Add them manually if they fall in the period.
Adding working days steps over Saturdays and Sundays. Ten working days from a Monday lands on the Friday of the following week — fourteen calendar days later. Public holidays are not deducted automatically because they vary by region.
How to add working days
Whether the starting day counts is a genuine convention difference. Most SLAs and legal notice periods start counting from the next working day, which is what this tool does — day one is the first working day after the start. Some contracts count the start day itself. Where it matters, name the target date rather than the count, because the two conventions differ by exactly one day and neither is obviously right.
