What's the date 100 years from today?

Solution

Wednesday June 20, 2125

0

100 years from today is 20 Jun 2125, a Wednesday. 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 Friday, well need to account for the weekend if you care about work days. If not, the calculation will remain the same. I usually just start with days of the week then move onto months. We’re 10 days from the end of June, so being in the middle of of the month, 100 days will bring us into July.. From there, we can then count forward by years and adjust for the fiscal calendar to get our 20 Jun 2125.

How we calculated 100 years from today

All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how adding 100 years to today's date gets calculated on each visit:

  • Started with date inputs: starting point: 20 Jun, Units to add: 100 years, and year: 2025
  • Noted your current time of year: 10 days in middle of June
  • Added 100 years from current day: 20 Jun, factoring in there are 10 days left in before July
  • Did NOT factor in workdays: In this calculation, we kept weekend. See below for just workdays or the 2025 fiscal calendar.

Tips to get your solution: June 20

Wednesday Wednesday June 20, 2125 is the 171 day of the year or 46.85% through 2125.

  • Current date: 20 Jun
  • Day of the week: Wednesday
  • New Date: Wednesday June 20, 2125
  • New Date Day of the week: Wednesday
  • June is the end of Q2 so if you're counting dates ahead, you might end up in H2 of the fiscal year.
  • The solution crosses into a different year..

Ways to calculate 100 years from today

  1. Just calculate it: Start with a time from today calculator. 100 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 2025. 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 June's calendar: Begin by identifying on a calendar, note that it’s Wednesday, and the total days in July (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 100 times by years, adding years from 20 Jun.
  3. Use Excel: Regardless of unit type, I use day calculations here. Type =TODAY()+100 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 100 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.

100 working years from today

100 years is Wednesday June 20, 2125 or could be Friday May 17, 2165 if you only want workdays. This calculation takes 100 years and only adds by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Wednesday June 20, 2125 date.
