What was the date 170 weeks ago?


Solution

Friday January 22, 2021


170 weeks ago from today was 22 Jan 2021, a Friday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 170 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 breaking calendar.day_name[solution.weekday()]n the year, then move into 170 weeks.

How we calculated 170 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 170 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 26 Apr, then set the calculation - 170 weeks, and factored in the year 2024
  2. Noted your current time of year: 170 weeks in April will bring us back to March or further.
  3. Counted backwards weeks from current day: date - 26 Apr, factoring in the 8 days left in April to calculate Friday January 22, 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 January 22

  • Current date: 26 Apr
  • Day of the week: Friday
  • New Date: Friday January 22, 2021
  • New Date Day of the week: Friday
  • Counting back form January will put you close, if not passed, 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 170 weeks ago

  1. Calculate it: Start with a time ago calculator. 170 weeks is easiest solved on a calculator. For ours, we've already factored in the 8 days in April + 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 April's calendar: Begin by identifying 26 Apr on a calendar, note that it’s Friday, and the total days in March (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 170 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()-170 to get or =WORKDAY(TODAY()), -170, cell:cell) for working weeks.

Working weeks in 170 calendar weeks

170 weeks is Friday January 22, 2021 or could be if you only want workdays. This calculation takes 170 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 January 22, 2021 date.
