100 days from today is 25 May 2025, a Sunday. Calculating the number of days that spans over three months from today moves us beyond mere day-to-day counting and into the realm of weekly and monthly converting which is mostly used in the fiscal calendar. We’ll need to consider the day of the week, length of February and March (and more), and the changing of the calendar. To start, today is a Sunday. 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.. Additionally, there are 14 days left of the 28 in February and since we’re in the middle of of the month, we’ll need to factor in shifting weekends of that quarter. Ultimately, adding if 100 days from today is difficult when the number is over a quarter and I’d recommend starting with a week conversion first.

How we calculated 100 days 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 days to today's date gets calculated on each visit:

  • Started with date inputs: starting point: 14 Feb, Units to add: 100 days, and year: 2025
  • Noted your current time of year: 14 days in middle of February
  • Added 100 days from current day: 14 Feb, factoring in there are 14 days left in before March
  • Did NOT factor in workdays: In this calculation, we kept weekend. See below for just workdays or the 2025 fiscal calendar.

Ways to calculate 100 days from today

  1. Just calculate it: Start with a time from today calculator. 100 days 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 days and choose the length of time, then click "calculate". This calculation does not factor in workdays or holidays (see below!).
  2. Use February's calendar: Begin by identifying on a calendar, note that it’s Sunday, and the total days in March (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 days, adding days from 14 Feb.
  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 days 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 days is Sunday May 25, 2025 or could be Friday July 04, 2025 if you only want workdays. This calculation takes 100 days and only adds by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Sunday May 25, 2025 date.
