What it does
Pick a date of birth and the calculator shows the exact age today in years, months and days, then the same age as totals in months, weeks and days, the weekday you were born on and how long until your next birthday. Change “Age on” to find the age on any other date, which is what most forms really ask: the age on an application deadline, a school start date or the day of an exam. It also converts the date of birth to the Hijri calendar and counts the age in Hijri years, which runs about one year ahead every 33 years because Hijri years are 11 days shorter. Hijri dates come from the Umm al-Qura calendar built into your browser. Someone born on 29 February is counted a year older on 28 February in common years.
How to use it
- In “Date of birth”, pick or type the date. On a phone, tap the field to open the date picker.
- “Age on” is filled in with today’s date. To find the age on another day, such as an application deadline, change it.
- The age appears in years, months and days, with the next birthday, totals in months, weeks and days, and the age in Hijri years.
- Click “Copy” to paste the age elsewhere, or “Today” to go back to today’s date.
Common uses
- Checking whether a child meets Egypt’s school entry age, which is counted on 1 October of the school year
- Filling in a job or visa application that asks for the age on the closing date, not on the day you apply
- Finding an age in Hijri years for a form or regulation that uses the Hijri calendar
- Counting the days until a birthday, or how many days old a baby is
Tips
- If a form sets an age limit “on” a date, put that date in “Age on”. A few days can decide whether someone is 17 or 18.
- A Hijri age is often one year more than the Gregorian age, and two more from about age 66, so check which calendar a form asks for before you fill it in.
- Typing a date is often faster than scrolling the picker on a computer: click the day, month or year and type the numbers.
