The more precise answer is: 60 years, 4 months and 13 days. This was calculated from the last day of 1965 (December 31) until today. For example, someone born in 1965 would be 60 or 61 years old. If they were born on or before May 14, they would be 61 years old and if were born after, 60 years old.
1965 was 60 years ago because we are now in 2026.
1965 was 724 months ago because we are now in May 2026. Here's how to calculate this: there are 12 months in a year so, 60 x 12 = 720. Four months have passed since the start of 2026 which also need to be added, meaning 720 + 4 = 724.
1965 was 3149 weeks ago. Although it may seem counterintuitive, the simplest approach is to first calculate the number of days since 1965 and divide that by 7 (the number of days in a week). In this particular situation, 22048 / 7 = 3149.71 from which we only need the whole number part, 3149.
1965 was 22048 days ago because today is May 14, 2026. Each typical year is at least 365 days long, so multiplying 60 years by 365 results in 21900. Factoring in the days passed since the beginning of this year we get 21900 + 133 = 22033. Of course, the 15 leap years during this period also have to accounted for. So adding 15 more days we end up with 22048 days in total.
As an academic exercise, it’s also possible to calculate how many hours passed since 1965. Given that we already know there are about 22048 days between then and now, we can multiply this number by 24 (the number of hours in a day) to get 529152 hours. Since it's currently 6:17 PM, we need to add the 18 hours that have passed since midnight to our subtotal of 529152. So 529152 + 18 = 529170, ergo 1965 was 529170 hours ago.
