COMMON QUESTIONS

Frequently asked questions

Does the calculator include today?

It measures the elapsed calendar difference between the two dates. The same date gives zero days.

Can I use a past date?

Yes. A past target is shown as days since that date.

Are weekends included?

Yes. This is a calendar-day countdown. Use the Working Days Calculator when weekends or bank holidays should be excluded.

Does daylight saving affect the answer?

No. The calculation uses date-only calendar differences rather than elapsed clock hours.
