What was the date 20 days ago?

Solution

Monday December 16, 2024

20 days ago from today was 16 Dec 2024, a Monday. When calculating a period over two weeks in the past, it's important to account for the day of the week. Since today is Sunday, the calculation could get a bit more complicated if you want to account for business days becuase it's the weekend. This takes our subtraction across multiple weeks, and with 5 days until the end of January counting backwards from today in the early part of of the month means that subtracting 20 days ago will bring us back to or further.

How we calculated 20 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 20 days ago gets calculated on each visit:

  1. We started with date inputs: used current day of 05 Jan, then set the calculation - 20 days, and factored in the year 2025
  2. Noted your current time of year: 20 days in January will bring us back to or further.
  3. Counted backwards days from current day: date - 05 Jan, factoring in the 5 days left in January to calculate Monday December 16, 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 16

  • Current date: 05 Jan
  • Day of the week: Monday
  • New Date: Monday December 16, 2024
  • New Date Day of the week: Monday
  • 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 20 days ago

  1. Calculate it: Start with a time ago calculator. 20 days is easiest solved on a calculator. For ours, we've already factored in the 5 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 05 Jan on a calendar, note that it’s Monday, 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 20 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()-20 to get or =WORKDAY(TODAY()), -20, cell:cell) for working days.

Working days in 20 calendar days

20 days is Monday December 16, 2024 or could be if you only want workdays. This calculation takes 20 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 December 16, 2024 date.
