The Pashut Neto age calculator computes your exact age on the Gregorian calendar: full years first, then full months, with the remainder in days — plus total days since birth and days until your next birthday. For example, someone born on 15.3.1990 is exactly 36 years, 4 months and 5 days old on 20.7.2026 — 13,276 days since birth.
How is it calculated?
The calculator first counts how many full years have passed since your birth date, then how many full months have passed since your last birthday, and the remainder is counted in days. Because month lengths differ — February has 28 or 29 days and the others 30 or 31 — you cannot simply divide days by 30; a true calendar computation that steps through the actual calendar is required, and that is exactly what the calculator does. It also computes total days since birth and the number of days left until your next birthday.
Example: born 15.3.1990 — 36 full years pass by 15.3.2026, 4 full months from 15.3.2026 to 15.7.2026, and 5 more days to 20.7.2026: in total 36 years, 4 months and 5 days, which is 13,276 days since birth, with 238 days until the next birthday on 15.3.2027. Everything is computed on the Gregorian calendar; a Hebrew-calendar birthday usually falls on a different Gregorian date each year.
Frequently asked questions
I was born on 29 February — when is my birthday?
The date 29.2 exists only in leap years — once every 4 years (except century years not divisible by 400, such as 1900). In common years most uses treat 1.3 as the birthday, and the original date returns only in the next leap year. Day counting is unaffected: someone born on 29.2.2000 completed exactly 9,497 days by 1.3.2026.
Why does my Hebrew birthday fall on a different date each year?
The Hebrew calendar is lunisolar: its common year is shorter than the Gregorian year, and every few years a leap month (Adar II) is added. As a result the Hebrew birthday drifts against the Gregorian calendar and can shift by two to three weeks from year to year. Events like a bar or bat mitzvah follow the Hebrew date, but this calculator computes age on the Gregorian calendar.
Which date counts for legal purposes — Gregorian or Hebrew?
For official and legal purposes in Israel, age is counted by the Gregorian birth date recorded in the Population Registry — for example age 16 for an ID card, 17 for a driving licence and 18 for voting. The Hebrew date appears on documents but is not the basis for legal age.
