151 weeks ago from today was 31 Dec 2021, a Friday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 151 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 1057 days on a calendar until getting my solution of Friday December 31, 2021.

How we calculated 151 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 151 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 22 Nov, then set the calculation - 151 weeks, and factored in the year 2024
  2. Noted your current time of year: 151 weeks in November will bring us back to October or further.
  3. Counted backwards weeks from current day: date - 22 Nov, factoring in the 22 days left in November to calculate Friday December 31, 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 December 31

  • Current date: 22 Nov
  • Day of the week: Friday
  • New Date: Friday December 31, 2021
  • New Date Day of the week: Friday
  • December marks the end of the year, so account for all the out of office notifications when counting backwards.
  • 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 151 weeks ago

  1. Calculate it: Start with a time ago calculator. 151 weeks is easiest solved on a calculator. For ours, we've already factored in the 22 days in November + 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 November's calendar: Begin by identifying 22 Nov on a calendar, note that it’s Friday, and the total days in October (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 151 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()-151 to get or =WORKDAY(TODAY()), -151, cell:cell) for working weeks.

Working weeks in 151 calendar weeks

151 weeks is Friday December 31, 2021 or could be if you only want workdays. This calculation takes 151 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 December 31, 2021 date.
