What was the date 399 weeks ago?


Solution

Sunday April 02, 2017

399 weeks ago from today was 02 Apr 2017, a Sunday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 399 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 2793 days on a calendar until getting my solution of Sunday April 02, 2017.

How we calculated 399 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 399 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 24 Nov, then set the calculation - 399 weeks, and factored in the year 2024
  2. Noted your current time of year: 399 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 April 02, 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 April 02

  • Current date: 24 Nov

  • New Date Day of the week: Sunday
  • 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)

  • The solution crosses into a different year.

Ways to calculate 399 weeks ago

  1. Calculate it: Start with a time ago calculator. 399 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 399 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()-399 to get or =WORKDAY(TODAY()), -399, cell:cell) for working weeks.

Working weeks in 399 calendar weeks

399 weeks is Sunday April 02, 2017 or could be if you only want workdays. This calculation takes 399 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 April 02, 2017 date.
