Frequently Asked Questions

How is exact age calculated?▾
Exact age counts completed calendar years, months, and days between your birth date and today. The algorithm first subtracts full years, then full months from the remainder, then remaining days — accounting for variable month lengths (28/29/30/31 days) and leap years. This differs from simply dividing total days by 365.25 because calendar months are not uniform.
How many days have I lived?▾
Total days lived = today minus birth date, counting every calendar day including the birth day. A 36-year-old born on a non-leap birthday has lived approximately 36 x 365.25 = 13,149 days. Leap years add one extra day every 4 years, so the exact count varies by birth year.
What is the life percentage calculation?▾
Life percentage = your age in years divided by reference life expectancy, times 100. The global average life expectancy is approximately 73 years (WHO 2024 data). For the UAE, life expectancy is approximately 79 years. A 36-year-old has used 36/73 = 49.3% of the global average.
How is the next birthday calculated for leap day birthdays?▾
People born on 29 February are treated as having a birthday of 28 February in non-leap years. In leap years, their true birthday falls on 29 February. The next birthday countdown shows days until 28 February in non-leap years and 29 February in leap years. The next leap year after 2024 is 2028.
What is my zodiac sign by birth date?▾
Western zodiac signs: Aries (21 Mar-19 Apr), Taurus (20 Apr-20 May), Gemini (21 May-20 Jun), Cancer (21 Jun-22 Jul), Leo (23 Jul-22 Aug), Virgo (23 Aug-22 Sep), Libra (23 Sep-22 Oct), Scorpio (23 Oct-21 Nov), Sagittarius (22 Nov-21 Dec), Capricorn (22 Dec-19 Jan), Aquarius (20 Jan-18 Feb), Pisces (19 Feb-20 Mar). Exact boundary dates shift by one day in some years due to the leap year cycle.
Can I calculate age between two custom dates?▾
Yes — the age calculator accepts any start and end date, not just birth date to today. Use it to calculate duration between any two historical or future dates: how long ago an event occurred, how long until a future milestone, or the age someone will be on a specific date.
How old am I in weeks, hours, and minutes?▾
Total weeks = days divided by 7. Total hours = days times 24. Total minutes = hours times 60. A 36-year-old has lived approximately 1,894 weeks, 317,400 hours, or 19,044,000 minutes. These numbers are approximate because they depend on exact time of birth.
What is the UAE official age of majority?▾
In the UAE, the age of majority is 21 years under Federal Law No. 5 of 1985 (Civil Transactions Law). Driving and voting: 18 years. Marriage minimum: 18 years (with court approval required for younger). Criminal responsibility begins at 7 years, with full responsibility at 18.
