Solution

Monday March 03, 2025

21 days ago from today was 03 Mar 2025, 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 Monday, we'll need to account for a full week before hitting weekend days. This takes our subtraction across multiple weeks, and with 24 days until the end of March counting backwards from today in the end of of the month means that subtracting 21 days ago will keep us in March and we don’t need to worry about adjusting months or years.

How we calculated 21 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 21 days ago gets calculated on each visit:

  1. We started with date inputs: used current day of 24 Mar, then set the calculation - 21 days, and factored in the year 2025
  2. Noted your current time of year: 21 days in March will keep us in March and we don’t need to worry about adjusting months or years.
  3. Counted backwards days from current day: date - 24 Mar, factoring in the 24 days left in March to calculate Monday March 03, 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 03

  • Current date: 24 Mar
  • Day of the week: Monday
  • New Date: Monday March 03, 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.

Ways to calculate 21 days ago

  1. Calculate it: Start with a time ago calculator. 21 days is easiest solved on a calculator. For ours, we've already factored in the 24 days in March + 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 March's calendar: Begin by identifying 24 Mar on a calendar, note that it’s Monday, and the total days in February (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 21 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()-21 to get or =WORKDAY(TODAY()), -21, cell:cell) for working days.

Working days in 21 calendar days

21 days is Monday March 03, 2025 or could be if you only want workdays. This calculation takes 21 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 03, 2025 date.
