If you were born on 1 January 1990, you are 36 years, 10 months and 10 days old today (11 November 2026) — 13,463 days old in total. Your next birthday is on Friday, 1 January 2027, in 51 days, when you will turn 37. This page gives your exact age, the milestone years, the leap days you have lived through, and the historical context of 1990.

Your exact age

This page uses 1 January 1990 as the birth date — the first day of the year. If you were born on a different day in 1990, your age in years is the same, but the months and days will differ: use the age calculator with your exact date of birth for the precise figure.

Measure Value
Age in years, months and days 36 years, 10 months, 10 days
Age in years 36
Total days lived 13,463
Total weeks lived 1,923
Total hours lived 323,112
Total minutes lived 19,386,720
Leap days lived through 9

The total days figure is the exact count from 1 January 1990 to 11 November 2026, including 9 leap days (29 February). The years-months-days figure is the same span expressed the way people usually talk about age: 36 full years since 1 January 1990, then 10 full months since 1 January 2026, then 10 days since 1 November 2026.

Your next birthday

Your next birthday is on Friday, 1 January 2027 — Friday — in 51 days. You will turn 37. Your birthday after that is on 1 January 2028, which is a Saturday. Birthdays on 1 January have one advantage: they are easy to remember, and they always fall on the same date — though the day of the week moves, because 1990 was not a leap year and the calendar shifts by one or two days each year. The birthday countdown counts down to your next birthday live.

Milestone years

The years in which you turned — or will turn — the ages that matter most:

Milestone Year Status in 2026
18 2008 Turned 18 in 2008
21 2011 Turned 21 in 2011
30 2020 Turned 30 in 2020
40 2030 Will turn 40 in 2030
50 2040 Will turn 50 in 2040
65 2055 Will turn 65 in 2055

You have already passed 18 (in 2008), 21 (in 2011), 30 (in 2020). Still to come: 40 (in 2030), 50 (in 2040), 65 (in 2055). The milestones that matter most in practice are 18 (voting and adulthood in most countries), 21 (drinking age in the United States), and 65 (retirement age and pension eligibility in many countries — though the exact age varies by country and by scheme).

The year 1990 — historical context

In 1990, Germany reunified, Nelson Mandela was released from prison, and the Hubble Space Telescope was launched.

The 1990s were the decade of the internet, the mobile phone and the end of the Cold War. For someone born in this decade, the defining years were the 2000s and 2010s — the smartphone, social media, and the financial crisis.

The calendar facts of 1990: 1 January 1990 was a Monday. 1990 was not a leap year, with 365 days. You have lived through 9 leap days since then — one for each leap year from 1990 to 2026 — and those days are counted in the total above.

Which generation are you?

Someone born in 1990 is part of the Millennials — the generation that came of age with the internet, the smartphone and the 2008 financial crisis. Generation labels are a shorthand, not a science: the boundaries are approximate, and demographers disagree about the exact years. The commonly used ranges are the Greatest Generation (1901–1927), the Silent Generation (1928–1945), the Baby Boomers (1946–1964), Generation X (1965–1980), the Millennials (1981–1996), Generation Z (1997–2012) and Generation Alpha (2013 onwards). On those ranges, 1990 falls in the Millennials.

Your birthdays through the years

Your birthday is on 1 January, so the day of the week moves by one each year — or by two after a leap year. The next five birthdays:

Birthday Date Day of the week Age you turn
2027 Friday, 1 January 2027 Friday 37
2028 Saturday, 1 January 2028 Saturday 38
2029 Monday, 1 January 2029 Monday 39
2030 Tuesday, 1 January 2030 Tuesday 40
2031 Wednesday, 1 January 2031 Wednesday 41

The pattern repeats every 28 years in most cases — the calendar cycle for birthdays — except across century years that are not leap years, like 2100, which break the pattern. Your birthday in 2030 will be on a Tuesday, when you turn 40. The day of the week calculator gives the weekday for any date, and the birthday countdown counts down to the next one.

Other birth years

If you were born in a different year, see 1989 or 1991 — every birth year from 1906 to 2025 has its own page, with the exact age, the milestones and the historical context. Or use the age calculator with your exact date of birth.
