What was the date 160 weeks ago?


Friday May 21, 2021


160 weeks ago from today was 21 May 2021, a Friday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 160 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 1120 days on a calendar until getting my solution of Friday May 21, 2021.

How we calculated 160 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 160 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 14 Jun, then set the calculation - 160 weeks, and factored in the year 2024
  2. Noted your current time of year: 160 weeks in June will bring us back to May or further.
  3. Counted backwards weeks from current day: date - 14 Jun, factoring in the 14 days left in June to calculate Friday May 21, 2021
  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 May 21

  • Current date: 14 Jun
  • Day of the week: Friday
  • New Date: Friday May 21, 2021
  • New Date Day of the week: Friday
  • Counting backward from May could put you back in Q1 or even the previous year.
  • This calculation crosses at least one month. Remeber, this will change our day of the week.
  • The solution crosses into a different year.
  • Your date will be a weekend. Consider if you only want workdays in your calculation.

Ways to calculate 160 weeks ago

  1. Calculate it: Start with a time ago calculator. 160 weeks is easiest solved on a calculator. For ours, we've already factored in the 14 days in June + 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 June's calendar: Begin by identifying 14 Jun on a calendar, note that it’s Friday, and the total days in May (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 160 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()-160 to get or =WORKDAY(TODAY()), -160, cell:cell) for working weeks.

Working weeks in 160 calendar weeks

160 weeks is Friday May 21, 2021 or could be if you only want workdays. This calculation takes 160 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Friday May 21, 2021 date.
