158 weeks ago from today was 29 Dec 2021, a Wednesday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2025. It looks like 158 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 1106 days on a calendar until getting my solution of Wednesday December 29, 2021.

How we calculated 158 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 158 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 08 Jan, then set the calculation - 158 weeks, and factored in the year 2025
  2. Noted your current time of year: 158 weeks in January will bring us back to or further.
  3. Counted backwards weeks from current day: date - 08 Jan, factoring in the 8 days left in January to calculate Wednesday December 29, 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 29

  • Current date: 08 Jan
  • Day of the week: Wednesday
  • New Date: Wednesday December 29, 2021
  • New Date Day of the week: Wednesday
  • 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.

Ways to calculate 158 weeks ago

  1. Calculate it: Start with a time ago calculator. 158 weeks is easiest solved on a calculator. For ours, we've already factored in the 8 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 08 Jan on a calendar, note that it’s Wednesday, 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 158 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()-158 to get or =WORKDAY(TODAY()), -158, cell:cell) for working weeks.

Working weeks in 158 calendar weeks

158 weeks is Wednesday December 29, 2021 or could be if you only want workdays. This calculation takes 158 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 December 29, 2021 date.
