Solution

Tuesday March 09, 2010

780 weeks ago from today was 09 Mar 2010, a Tuesday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2025. It looks like 780 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 5460 days on a calendar until getting my solution of Tuesday March 09, 2010.

How we calculated 780 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 780 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 18 Feb, then set the calculation - 780 weeks, and factored in the year 2025
  2. Noted your current time of year: 780 weeks in February will bring us back to January or further.
  3. Counted backwards weeks from current day: date - 18 Feb, factoring in the 18 days left in February to calculate Tuesday March 09, 2010
  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 March 09

  • Current date: 18 Feb
  • Day of the week: Tuesday
  • New Date: Tuesday March 09, 2010
  • New Date Day of the week: Tuesday
  • March is usually not, but sometimes super tricky. Factor in Leap Years and Easter, which falls on varying dates each year, if you need a date in the past.
  • 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 780 weeks ago

  1. Calculate it: Start with a time ago calculator. 780 weeks is easiest solved on a calculator. For ours, we've already factored in the 18 days in February + 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 February's calendar: Begin by identifying 18 Feb on a calendar, note that it’s Tuesday, and the total days in January (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 780 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()-780 to get or =WORKDAY(TODAY()), -780, cell:cell) for working weeks.

Working weeks in 780 calendar weeks

780 weeks is Tuesday March 09, 2010 or could be if you only want workdays. This calculation takes 780 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Tuesday March 09, 2010 date.
