What was the date 450 weeks ago?

Solution

Saturday December 12, 2015

450 weeks ago from today was 12 Dec 2015, a Saturday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 450 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 3150 days on a calendar until getting my solution of Saturday December 12, 2015.

How we calculated 450 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 450 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 27 Jul, then set the calculation - 450 weeks, and factored in the year 2024
  2. Noted your current time of year: 450 weeks in July will bring us back to June or further.
  3. Counted backwards weeks from current day: date - 27 Jul, factoring in the 27 days left in July to calculate Saturday December 12, 2015
  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 12

  • Current date: 27 Jul
  • Day of the week: Saturday
  • New Date: Saturday December 12, 2015
  • New Date Day of the week: Saturday
  • 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.
  • Your date will be a weekend. Consider if you only want workdays in your calculation.

Ways to calculate 450 weeks ago

  1. Calculate it: Start with a time ago calculator. 450 weeks is easiest solved on a calculator. For ours, we've already factored in the 27 days in July + 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 July's calendar: Begin by identifying 27 Jul on a calendar, note that it’s Saturday, and the total days in June (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 450 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()-450 to get or =WORKDAY(TODAY()), -450, cell:cell) for working weeks.

Working weeks in 450 calendar weeks

450 weeks is Saturday December 12, 2015 or could be if you only want workdays. This calculation takes 450 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 December 12, 2015 date.
