A more precise answer is: 36 years, 8 months and 25 days. For this calculation, December 31, 1989 was chosen as the starting date until today. Now if you are wondering how old is someone born in 1989, they would be either 36 or 37 years old depending on their birth date. A person born on or before September 26 is 37 years old, while one born after that date is 36 years old.
1989 was 36 years ago because we are now in 2026.
1989 was 440 months ago because we’re currently in September 2026. Here's how to calculate this: each year has 12 months so, 36 x 12 = 432. Add the 8 months passed since the beginning of 2026 and you get, 432 + 8 = 440.
1989 was 1916 weeks ago. The trick to finding this result lies in calculating how many days have passed since 1989 and divide that number by 7 (days in a week). In this particular case, 13417 / 7 = 1916.71, from which only the quotient is needed, 1916.
1989 was 13417 days ago because today is September 26, 2026. Each year has at least 365 days, so 36 x 365 = 13140. To this we add the days passed since the beginning of 2026. Then we have 13140 + 268 = 13408. But what about leap years? Yes, there were 9 leap years since 1989, so we also need to add 9 extra days for a total of 13417.
As an academic exercise, it’s also possible to calculate how many hours passed since 1989. Given that we already know there are about 13417 days between then and now, we can multiply this number by 24 (the number of hours in a day) to get 322008 hours. Since it's currently 10:56 PM, we need to add the 22 hours that have passed since midnight to our subtotal of 322008. So 322008 + 22 = 322030, ergo 1989 was 322030 hours ago.
