Percentage Calculator
What X% of a number is, percentage increase and decrease, and what percent one number is of another.
Work out your exact age in years, months and days from your date of birth, on today’s date or on any date you choose — plus your total days, total weeks, and days until your next birthday. Your dates stay in your browser: your date of birth is not stored.
Enter as day / month / year, for example 15/03/1995, using the date picker. 03/04/2000 means 3 April 2000.
Born on 29 February? In years without a 29 February, your completed years count from 1 March, and your next birthday is shown as 1 March.

Gregorian calendar. “Today” is the date in Asia/Karachi. 29 February birthdays count from 1 March in non-leap years.
Your date of birth is not stored.
The years, months and days are counted by calendar borrowing: first the completed years, then the completed months, then the remaining days — not by dividing total days by 365. Total days are counted by subtracting the two calendar dates, so leap days are included exactly.
Born on 29 February? In a year without 29 February, your completed years count from 1 March, and your next birthday is shown as 1 March. In a leap year, your birthday is 29 February itself.
“Today” means the calendar date in Pakistan (Asia/Karachi) when you calculate. The time of day does not change the result.
Born 15 March 1995, age at 28 October 2026: 31 years, 7 months, 13 days; 11,550 days; 1,650 weeks, 0 days; 379 complete months; born on a Wednesday; next birthday 15 March 2027 (Monday), 138 days away.
Enter your date of birth and, if you want, a different “age at” date. The calculator counts completed years, then completed months, then remaining days, and shows the result in the result card.
The result shows your next birthday — the next occurrence of your birth month and day strictly after the “age at” date — and how many days away it is. On your birthday itself, the next birthday shown is next year’s.
In a leap year, your birthday is 29 February. In a year without 29 February, your completed years count from 1 March, and your next birthday is shown as 1 March.
Use the date picker to enter dates in day / month / year (DD/MM/YYYY) order — for example, 03/04/2000 means 3 April 2000. Results show dates in full, for example 15 March 1995, so there is no ambiguity.
No. The calculation runs in your browser. Your date of birth is not stored, sent to a server, or included in a web address. Reloading the page clears the form.
