How we calculated 42 weeks 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 42 weeks to today's date gets calculated on each visit:

  • Started with date inputs: starting point: 21 Nov, Units to add: 42 weeks, and year: 2024
  • Noted your current time of year: 9 days in end of November
  • Added 42 weeks from current day: 21 Nov, factoring in there are 9 days left in before December
  • Did NOT factor in workdays: In this calculation, we kept weekend. See below for just workdays or the 2024 fiscal calendar.

Tips to get your solution: September 11

Thursday Thursday September 11, 2025 is the 254 day of the year or 69.59% through 2025.

  • Current date: 21 Nov
  • Day of the week: Thursday
  • New Date: Thursday September 11, 2025
  • New Date Day of the week: Thursday
  • Consider Thanksgiving and time off when counting dates from November.
  • This calculation crosses at least one month. Remeber, this will change our day of the week.
  • The solution crosses into a different year..

Ways to calculate 42 weeks from today

  1. Just calculate it: Start with a time from today calculator. 42 weeks 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 weeks and choose the length of time, then click "calculate". This calculation does not factor in workdays or holidays (see below!).
  2. Use November's calendar: Begin by identifying on a calendar, note that it’s Thursday, and the total days in December (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 42 times by weeks, adding weeks from 21 Nov.
  3. Use Excel: Regardless of unit type, I use day calculations here. Type =TODAY()+42 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 42 weeks 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.

42 working weeks from today

42 weeks is Thursday September 11, 2025 or could be Monday January 05, 2026 if you only want workdays. This calculation takes 42 weeks and only adds by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Thursday September 11, 2025 date.
