What was the date 100 weeks ago?

Solution

Friday April 28, 2023

Date Range: 100 weeks

100 weeks ago from today was 28 Apr 2023, a Friday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2025. It looks like 100 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 700 days on a calendar until getting my solution of Friday April 28, 2023.

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 28 Mar, then set the calculation - 100 weeks, and factored in the year 2025
  2. Noted your current time of year: 100 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 April 28, 2023
  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 April 28

  • Current date: 28 Mar
  • Day of the week: Friday
  • New Date: Friday April 28, 2023
  • New Date Day of the week: Friday
  • April is the end of the quarter and the beginning of spring. It's also Phillies Opening Day, so plan according and take the week off work! (Go Phils)
  • 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 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 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 Friday April 28, 2023 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 Friday April 28, 2023 date.
