What was the date 180 weeks ago?

Solution

Friday October 15, 2021

Date Range: 180 weeks

180 weeks ago from today was 15 Oct 2021, a Friday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2025. It looks like 180 weeks from now will bring us back to pre 2024 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 1260 days on a calendar until getting my solution of Friday October 15, 2021.

How we calculated 180 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 180 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 28 Mar, then set the calculation - 180 weeks, and factored in the year 2025
  2. Noted your current time of year: 180 weeks in March will bring us back to February or further.
  3. Counted backwards weeks from current day: date - 28 Mar, factoring in the 28 days left in March to calculate Friday October 15, 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 October 15

  • Current date: 28 Mar
  • Day of the week: Friday
  • New Date: Friday October 15, 2021
  • New Date Day of the week: Friday
  • October marks the start of Q4 so counting backward will put you back into the 3 fiscal quarter.
  • 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 180 weeks ago

  1. Calculate it: Start with a time ago calculator. 180 weeks is easiest solved on a calculator. For ours, we've already factored in the 28 days in March + 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 March's calendar: Begin by identifying 28 Mar on a calendar, note that it’s Friday, 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 180 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()-180 to get or =WORKDAY(TODAY()), -180, cell:cell) for working weeks.

Working weeks in 180 calendar weeks

180 weeks is Friday October 15, 2021 or could be if you only want workdays. This calculation takes 180 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 October 15, 2021 date.
