A more accurate response: 24 years, 4 months and 13 days. This duration was calculated from December 31, 2001 until today's date. For instance, someone born in 2001 would be either 24 or 25 years old. If their birthday falls on or before May 14, they are 25, if it’s after May 14, they are 24.
2001 was 24 years ago because we are now in 2026.
2001 was 292 months ago because we’re currently in May 2026. Here's how to calculate this: each year has 12 months so, 24 x 12 = 288. Add the 4 months passed since the beginning of 2026 and you get, 288 + 4 = 292.
2001 was 1271 weeks ago. Although it may seem counterintuitive, the simplest approach is to first calculate the number of days since 2001 and divide that by 7 (the number of days in a week). In this particular situation, 8899 / 7 = 1271.29 from which we only need the whole number part, 1271.
2001 was 8899 days ago because today is May 14, 2026. Since each year has at least 365 days, we get 24 x 365 = 8760. Next, we need to add the days passed since the beginning of 2026. Then we have 8760 + 133 = 8893. Finally, we take into account the leap years. There were 6 leap years since 2001, so we also have to add 6 more days for a total of 8899.
If you want to, you can take it up one step further. You can also calculate how many hours passed since 2001. Since we already know the number of days, it would be 24 x 8899 = 213576. Right now it’s 6:20 PM, meaning we have to add 18 (hours passed since midnight) to 213576. So 2001 was 213594 hours ago.
A lot happened in 2001. For a quick look at the most memorable events, here is the “The Year In Pictures 2001” cover from LIFE Magazine.
