What was the date 21 weeks ago?

Solution

Sunday August 11, 2024

21 weeks ago from today was 11 Aug 2024, a Sunday. We’re now subtracting quarters of the year. This means 21 weeks from 05 Jan changes fiscal calendars and could even push us into previous years. We’re currently in early part of January with 5 days left; this will bring us back to or further. When I calculate backwards for larger weeks before today, I like to start by subtracting the days, then count backwards to find the correct weeks.

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

  1. We started with date inputs: used current day of 05 Jan, then set the calculation - 21 weeks, and factored in the year 2025
  2. Noted your current time of year: 21 weeks in January will bring us back to or further.
  3. Counted backwards weeks from current day: date - 05 Jan, factoring in the 5 days left in January to calculate Sunday August 11, 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 August 11

  • Current date: 05 Jan
  • Day of the week: Sunday
  • New Date: Sunday August 11, 2024
  • New Date Day of the week: Sunday
  • August is the beginning of Q3. Dates in previous months will be part of 1H fiscal years.
  • 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 21 weeks ago

  1. Calculate it: Start with a time ago calculator. 21 weeks 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 weeks 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 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 21 times weeks by weeks, subtracting weeks from until your remainder of weeks is 0.
  3. Use excel: For more complex weeks 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 weeks.

Working weeks in 21 calendar weeks

21 weeks is Sunday August 11, 2024 or could be if you only want workdays. This calculation takes 21 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Sunday August 11, 2024 date.
