623 weeks ago from today was 17 Dec 2012, a Monday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 623 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 4361 days on a calendar until getting my solution of Monday December 17, 2012.

How we calculated 623 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 623 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 25 Nov, then set the calculation - 623 weeks, and factored in the year 2024
  2. Noted your current time of year: 623 weeks in November will bring us back to October or further.
  3. Counted backwards weeks from current day: date - 25 Nov, factoring in the 25 days left in November to calculate Monday December 17, 2012
  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 17

  • Current date: 25 Nov
  • Day of the week: Monday
  • New Date: Monday December 17, 2012
  • New Date Day of the week: Monday
  • 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 623 weeks ago

  1. Calculate it: Start with a time ago calculator. 623 weeks is easiest solved on a calculator. For ours, we've already factored in the 25 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 25 Nov on a calendar, note that it’s Monday, 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 623 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()-623 to get or =WORKDAY(TODAY()), -623, cell:cell) for working weeks.

Working weeks in 623 calendar weeks

623 weeks is Monday December 17, 2012 or could be if you only want workdays. This calculation takes 623 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Monday December 17, 2012 date.
