What was the date 100 weeks ago?


Solution

Saturday June 25, 2022

0

100 weeks ago from today was 25 Jun 2022, a Saturday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 100 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 700 days on a calendar until getting my solution of Saturday June 25, 2022.

How we calculated 100 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 100 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 25 May, then set the calculation - 100 weeks, and factored in the year 2024
  2. Noted your current time of year: 100 weeks in May will bring us back to April or further.
  3. Counted backwards weeks from current day: date - 25 May, factoring in the 25 days left in May to calculate Saturday June 25, 2022
  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 June 25

  • Current date: 25 May
  • Day of the week: Saturday
  • New Date: Saturday June 25, 2022
  • New Date Day of the week: Saturday
  • June is the beginning of summer so be careful, counting backwards could put you in the chilly months of spring and winter.
  • 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 100 weeks ago

  1. Calculate it: Start with a time ago calculator. 100 weeks is easiest solved on a calculator. For ours, we've already factored in the 25 days in May + 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 May's calendar: Begin by identifying 25 May on a calendar, note that it’s Saturday, and the total days in April (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 100 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()-100 to get or =WORKDAY(TODAY()), -100, cell:cell) for working weeks.

Working weeks in 100 calendar weeks

100 weeks is Saturday June 25, 2022 or could be if you only want workdays. This calculation takes 100 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Saturday June 25, 2022 date.
