What was the date 31 days ago?

Solution

Monday March 17, 2025

Date Range: 31 days

31 days ago from today was 17 Mar 2025, a Monday. 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 Thursday, we'll have to adjust for the weekend, if you care about the number of work days. Counting backwards from today skips several weekends, meaning that subtracting 31 days takes us from the middle of of April to potentially crossing far beyond April or March. For those of us focusing on workdays, subtracting 31 days ago necessitates adjustments for the fiscal calendar (don’t worry, I've accounted for it below).

How we calculated 31 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 31 days ago gets calculated on each visit:

  1. We started with date inputs: used current day of 17 Apr, then set the calculation - 31 days, and factored in the year 2025
  2. Noted your current time of year: 31 days in April will bring us back to March or further.
  3. Counted backwards days from current day: date - 17 Apr, factoring in the 17 days left in April to calculate Monday March 17, 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 17

  • Current date: 17 Apr
  • Day of the week: Monday
  • New Date: Monday March 17, 2025
  • New Date Day of the week: Monday
  • 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 31 days ago

  1. Calculate it: Start with a time ago calculator. 31 days is easiest solved on a calculator. For ours, we've already factored in the 17 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 17 Apr on a calendar, note that it’s Monday, 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 31 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()-31 to get or =WORKDAY(TODAY()), -31, cell:cell) for working days.

Working days in 31 calendar days

31 days is Monday March 17, 2025 or could be if you only want workdays. This calculation takes 31 days and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Monday March 17, 2025 date.
