What's the date 77 years from today?


Friday July 15, 2101


77 years from today is 15 Jul 2101, a Friday. Counting forward by years is usually simple. Anything under a decade can usually be done on one hand; however, remember that years will change the final date depending on leap years. Since today is Monday, we'll need to account for a full week before hitting weekend days. I usually just start with days of the week then move onto months. We’re 16 days from the end of July, so being in the middle of of the month, 77 days will bring us into August.. From there, we can then count forward by years and adjust for the fiscal calendar to get our 15 Jul 2101.

Ways to calculate 77 years from today

  1. Just calculate it: Start with a time from today calculator. 77 years is easiest solved on a calculator. For ours, we've already factored in the days in + all number of days in each month and the number of days in 2024. Simply add your years and choose the length of time, then click "calculate". This calculation does not factor in workdays or holidays (see below!).
  2. Use July's calendar: Begin by identifying on a calendar, note that it’s Friday, and the total days in August (trust me, you’ll need this for smaller calculations) and days until next year (double trust me, you'll need this for larger calculations). From there, count forward 77 times by years, adding years from 15 Jul.
  3. Use Excel: Regardless of unit type, I use day calculations here. Type =TODAY()+77 into the cell. If you want to add weeks, multiply your day by 7 and months/years will take their own calculation due to the changing days of the week. To find 77 years workdays, convert to days but use =WORKDAY(TODAY(), [number of days], [holidays]) into the cell. [number of days] is how many working days you want to add, and [holidays] is an optional range of cells that contain dates of holidays to exclude.
