About Days Between Dates
Find the exact gap between two dates — in days, weeks, months and years, plus a business-day count that skips weekends. Handy for project deadlines, notice periods, contract terms and counting down to an event.
How to use it
- Pick a start date and an end date.
- Choose whether to include the end date in the count.
- Read the duration, and switch to business days to exclude weekends.
Frequently asked questions
Is the end date included?
By default no — the count is the gap between the dates. Toggle "include end date" when counting something like a hotel stay or a notice period where both endpoints count.
How are leap years handled?
Automatically. The calculation uses real calendar dates, so 29 February is counted whenever it falls inside the range.
Does the business-day count know about public holidays?
No. It excludes Saturdays and Sundays only, since public holidays differ by country and region.

SIP Calculator guide
A Systematic Investment Plan is a standing instruction to put a fixed amount into a mutual fund on the same date each month. That is the whole idea. It is not a product you buy, not an asset class, and not a scheme with a guaranteed rate — it is a schedule. The returns come from whatever the underlying fund holds.

BMI Calculator guide
Body Mass Index is weight in kilograms divided by height in metres squared. That is the whole calculation. It was devised in the 1830s by the Belgian statistician Adolphe Quetelet, who was explicitly describing populations rather than assessing individuals — a distinction that matters enormously and gets lost constantly.

Almost every percentage problem is one of four shapes. Knowing which one you are looking at is most of the work, because each has a different formula and mixing them up is where the wrong answers come from.
