What was the date 109 weeks ago?

Solution

Wednesday September 21, 2022

109 weeks ago from today was 21 Sep 2022, a Wednesday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 109 weeks from now will bring us back to pre 2023 and we’ll need to factor this into our subtraction because it will change the calendar and fiscal years. For larger calculations like this, I start by subtracting total days, then counting backwards 763 days on a calendar until getting my solution of Wednesday September 21, 2022.

How we calculated 109 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 109 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 23 Oct, then set the calculation - 109 weeks, and factored in the year 2024
  2. Noted your current time of year: 109 weeks in October will bring us back to September or further.
  3. Counted backwards weeks from current day: date - 23 Oct, factoring in the 23 days left in October to calculate Wednesday September 21, 2022
  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 September 21

  • Current date: 23 Oct
  • Day of the week: Wednesday
  • New Date: Wednesday September 21, 2022
  • New Date Day of the week: Wednesday
  • Counting backward from September puts you back into the summer! September is the official start of fall.
  • 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 109 weeks ago

  1. Calculate it: Start with a time ago calculator. 109 weeks is easiest solved on a calculator. For ours, we've already factored in the 23 days in October + 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 October's calendar: Begin by identifying 23 Oct on a calendar, note that it’s Wednesday, and the total days in September (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 109 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()-109 to get or =WORKDAY(TODAY()), -109, cell:cell) for working weeks.

Working weeks in 109 calendar weeks

109 weeks is Wednesday September 21, 2022 or could be if you only want workdays. This calculation takes 109 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Wednesday September 21, 2022 date.
