COMMON QUESTIONS

Frequently asked questions

How many days are in a week?

This calculator uses seven calendar days per week.

Are the start and end dates included?

By default the start date is excluded and the end date is included, matching a standard elapsed-date difference.

Can I count working weeks instead?

Use the Working Days Calculator when weekends or UK bank holidays should be excluded.

Why are decimal weeks different from full weeks?

Decimal weeks divide total days by seven, while full weeks show only complete seven-day blocks plus remaining days.
