Pick a start and end date to get the number of calendar days between them, the same span in years, months and days, weeks and days, weekdays (Monday to Friday) and weekend days, with an option to count the end date too.
What does this tool do?
Counts the days, weeks, months and years between two dates — for tenures, ages, project durations, notice periods and countdowns. Includes/excludes the end date as you choose, and lists total days alongside calendar breakdowns.
It is designed for repeated use: change any input and every dependent figure recalculates immediately, so comparing scenarios — a higher rate versus a shorter tenure, this month versus last — takes seconds rather than a fresh spreadsheet. The layout keeps the headline result prominent while the working stays visible for anyone who wants to check the math.
Using it is simple: the inputs are “Start date” and “End date”. Results update live as you work — there is no waiting and nothing to submit.
How do I use this tool?
Enter your figures below — every result updates the instant you type, so comparing scenarios is just a matter of changing a number and watching the answer move.
- Enter your values in “Start date”, “End date”.
- Results update instantly as you type — no button to press.
How does it work?
Day counts use actual calendar arithmetic (leap years included); the calendar breakdown counts whole years, then whole months, then leftover days — the same borrowing method as the age calculator. Weekday counts tally actual weekdays in the range.
The formula used is the standard one taught and published for this calculation — the tool does not invent methods. Where conventions differ (rounding, day-count, tax treatment), the page follows the common Pakistani practice and says so, so the result matches what local institutions expect.
Use cases in Pakistan
HR departments compute service length for gratuity and leave encashment; tenants count agreement durations; students count days to CSS/MDCAT exams; and families count the days between nikkah and rukhsati. The weekday count helps payroll for daily-wage calculations.
Families use it for household budgeting and school-fee planning; small businesses for pricing and payroll math; students for everything from BISE numericals to CSS preparation. Wherever the same calculation is repeated monthly — bills, salaries, savings targets — this page replaces the phone-calculator ritual.
Limitations
Month/year breakdowns are calendar-based, not fixed 30-day blocks — two “3-month” periods can differ in days. For legal deadlines, confirm whether the end date counts and which calendar (Gregorian/Hijri) the contract uses.
Assumptions are stated on the page — read them before trusting the headline number for money, health or legal decisions. A calculator amplifies the quality of its inputs: careful numbers in, trustworthy numbers out.
Frequently asked questions
How many days between two dates?
Enter both dates above — total days, weeks and the calendar breakdown appear instantly. For figures that go into applications or documents, double-check the inputs against the source — the math is exact, but only for the numbers you enter.
Does it count the end date?
You choose: inclusive or exclusive counting, since contracts differ. Pick the mode that matches your need. Try varying one input at a time to see which assumption drives the result; that sensitivity check is often more valuable than the headline number.
How many working days?
The weekday tally excludes weekends; subtract public holidays manually for exact working days. Save or screenshot the result with its inputs when the figure matters later — reconstructing “what did I enter?” is harder than it sounds.
Why not just divide by 30?
Months vary (28–31 days) and leap years add days — real calendar math is the only correct way. For figures that go into applications or documents, double-check the inputs against the source — the math is exact, but only for the numbers you enter.
Is my data uploaded or stored?
No. This tool runs entirely in your browser — what you type or paste never leaves your device, is never sent to a server, and is never stored. Closing the tab removes all trace. Try varying one input at a time to see which assumption drives the result; that sensitivity check is often more valuable than the headline number.
Is it really free? Do I need an account?
Yes, free, and no account needed. Open the page and use it — no sign-up, no trial, no watermark on results. Save or screenshot the result with its inputs when the figure matters later — reconstructing “what did I enter?” is harder than it sounds.
