What was the date 31 days ago?

Solution

Sunday December 29, 2024

0

31 days ago from today was 29 Dec 2024, a Sunday. As we approach calculations over month in the past, the 31 days in January play significant roles, alongside the day of the week. Since today is Wendesday, we'll actually need to start considering the weekend. Two days from now the weekend begins and it could throw off our calculation if we consider work days. Counting backwards from today skips several weekends, meaning that subtracting 31 days takes us from the end of of January to potentially crossing far beyond January or . 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 29 Jan, then set the calculation - 31 days, and factored in the year 2025
  2. Noted your current time of year: 31 days in January will bring us back to or further.
  3. Counted backwards days from current day: date - 29 Jan, factoring in the 29 days left in January to calculate Sunday December 29, 2024
  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 December 29

  • Current date: 29 Jan
  • Day of the week: Sunday
  • New Date: Sunday December 29, 2024
  • New Date Day of the week: Sunday
  • December marks the end of the year, so account for all the out of office notifications when counting backwards.
  • 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 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 29 days in January + 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 January's calendar: Begin by identifying 29 Jan on a calendar, note that it’s Sunday, and the total days in (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 Sunday December 29, 2024 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 Sunday December 29, 2024 date.
