The more precise answer is: 40 years, 4 months and 13 days. This was calculated from the last day of 1985 (December 31) until today. For example, someone born in 1985 would be 40 or 41 years old. If they were born on or before May 14, they would be 41 years old and if were born after, 40 years old.
1985 was 40 years ago because we are now in 2026.
1985 was 484 months ago because it’s May 2026. The calculation is straightforward: each year has 12 months, 40 x 12 = 480. Then, considering four months have passed since the beginning of 2026 you have 480 + 4 = 484.
1985 was 2106 weeks ago. The trick I like to use is to first calculate how many days have passed since 1985 and divide that number by 7 (days in a week). In short, 14743 / 7 = 2106.14, but only the quotient is relevant here, 2106.
1985 was 14743 days ago because today is May 14, 2026. Since each year has at least 365 days, we get 40 x 365 = 14600. Next, we need to add the days passed since the beginning of 2026. Then we have 14600 + 133 = 14733. Finally, we take into account the leap years. There were 10 leap years since 1985, so we also have to add 10 more days for a total of 14743.
For a little bit of fun, you can also calculate how many hours it's been since 1985. Take the number of days and multiply it by 24 (hours in a day) 24 x 14743 = 353832. Then add the hours passed since midnight 353832 + 18 = 353850 and there you have it: 1985 was 353850 hours ago.
