What was the date 40 days ago?

Solution

Thursday March 20, 2025

0

40 days ago from today was 20 Mar 2025, a Thursday. As we approach calculations over month in the past, the 30 days in April play significant roles, alongside the day of the week. Since today is Tuesday and still part of the beginning of the week we won't need to add additional days into next week. Counting backwards from today skips several weekends, meaning that subtracting 40 days takes us from the end of of April to potentially crossing far beyond April or March. For those of us focusing on workdays, subtracting 40 days ago necessitates adjustments for the fiscal calendar (don’t worry, I've accounted for it below).

How we calculated 40 days before 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 40 days ago gets calculated on each visit:

  1. We started with date inputs: used current day of 29 Apr, then set the calculation - 40 days, and factored in the year 2025
  2. Noted your current time of year: 40 days in April will bring us back to March or further.
  3. Counted backwards days from current day: date - 29 Apr, factoring in the 29 days left in April to calculate Thursday March 20, 2025
  4. Did NOT factor in workdays: In this calculation, we kept weekend. See below for just workdays or the fiscal calendar

Tips when solving for March 20

  • Current date: 29 Apr
  • Day of the week: Thursday
  • New Date: Thursday March 20, 2025
  • New Date Day of the week: Thursday
  • March is usually not, but sometimes super tricky. Factor in Leap Years and Easter, which falls on varying dates each year, if you need a date in the past.
  • This calculation crosses at least one month. Remeber, this will change our day of the week.

Ways to calculate 40 days ago

  1. Calculate it: Start with a time ago calculator. 40 days is easiest solved on a calculator. For ours, we've already factored in the 29 days in April + all number of days in each month and the number of days in . 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 April's calendar: Begin by identifying 29 Apr on a calendar, note that it’s Thursday, and the total days in March (trust me, you’ll need this for smaller calculations) and days until last year (double trust me, you'll need this for larger calculations). From there, count backwards 40 times days by days, subtracting days from until your remainder of days is 0.
  3. Use excel: For more complex days calculations or if you h8 our site (kidding), I use Excel functions like =TODAY()-40 to get or =WORKDAY(TODAY()), -40, cell:cell) for working days.

Working days in 40 calendar days

40 days is Thursday March 20, 2025 or could be if you only want workdays. This calculation takes 40 days and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Thursday March 20, 2025 date.
