What was the date 800 weeks ago?

Solution

Saturday November 14, 2009

800 weeks ago from today was 14 Nov 2009, a Saturday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2025. It looks like 800 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 5600 days on a calendar until getting my solution of Saturday November 14, 2009.

How we calculated 800 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 800 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 15 Mar, then set the calculation - 800 weeks, and factored in the year 2025
  2. Noted your current time of year: 800 weeks in March will bring us back to February or further.
  3. Counted backwards weeks from current day: date - 15 Mar, factoring in the 15 days left in March to calculate Saturday November 14, 2009
  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 November 14

  • Current date: 15 Mar
  • Day of the week: Saturday
  • New Date: Saturday November 14, 2009
  • New Date Day of the week: Saturday
  • In Novemeber, account for the end of the year holidays 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.
  • Your date will be a weekend. Consider if you only want workdays in your calculation.

Ways to calculate 800 weeks ago

  1. Calculate it: Start with a time ago calculator. 800 weeks is easiest solved on a calculator. For ours, we've already factored in the 15 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 15 Mar on a calendar, note that it’s Saturday, 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 800 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()-800 to get or =WORKDAY(TODAY()), -800, cell:cell) for working weeks.

Working weeks in 800 calendar weeks

800 weeks is Saturday November 14, 2009 or could be if you only want workdays. This calculation takes 800 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 November 14, 2009 date.
