How this calculator counts
Business days are counted by excluding Saturdays, Sundays and the UK bank holidays listed in this site. For legal, contractual or court deadlines, always check the rule that applies to your situation.

Ten business days is two working weeks
Ten business days equals two full working weeks. In calendar terms it is usually 14 days, because two weekends fall inside the window. With one bank holiday in the period it becomes 15 calendar days; with two, 16.
The most common mistake is adding ten to the date and treating weekends as if they counted. That lands you roughly four days early.
Worked example
Starting Monday 5 October 2026, the first business day is Tuesday 6 October, so the tenth business day is Monday 19 October 2026 — two weekends later, with no bank holiday in between.
If the window included a bank holiday, the same calculation would finish one working day later. The calculator applies the site's UK bank holiday list automatically.
Where a ten-business-day window is used
Ten working days is the shape of many internal response targets, two-week procurement or quotation windows, and contractual notice to remedy. It is long enough that people stop counting carefully, which is exactly when the weekend arithmetic goes wrong.
FAQs
Does today count as a business day?
This calculator starts counting after the start date for "from" calculations, which is common for deadline planning. Check your specific rule if today should count as day one.
Are bank holidays excluded?
Yes, the calculator excludes the UK bank holidays held in the site calendar.
Is ten business days the same as 14 days?
Usually, but not always. It is 14 calendar days only when no bank holiday falls inside the two-week window.
Do weekends count towards ten business days?
No. Saturdays and Sundays are excluded, as are the UK bank holidays listed on this site.
