What was the date 360 weeks ago?

Solution

Sunday December 31, 2017

360 weeks ago from today was 31 Dec 2017, a Sunday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 360 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 2520 days on a calendar until getting my solution of Sunday December 31, 2017.

How we calculated 360 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 360 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 24 Nov, then set the calculation - 360 weeks, and factored in the year 2024
  2. Noted your current time of year: 360 weeks in November will bring us back to October or further.
  3. Counted backwards weeks from current day: date - 24 Nov, factoring in the 24 days left in November to calculate Sunday December 31, 2017
  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 31

  • Current date: 24 Nov
  • Day of the week: Sunday
  • New Date: Sunday December 31, 2017
  • New Date Day of the week: Sunday
  • 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 360 weeks ago

  1. Calculate it: Start with a time ago calculator. 360 weeks is easiest solved on a calculator. For ours, we've already factored in the 24 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 24 Nov on a calendar, note that it’s Sunday, 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 360 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()-360 to get or =WORKDAY(TODAY()), -360, cell:cell) for working weeks.

Working weeks in 360 calendar weeks

360 weeks is Sunday December 31, 2017 or could be if you only want workdays. This calculation takes 360 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Sunday December 31, 2017 date.
