What was the date 485 weeks ago?

Solution

Wednesday December 30, 2015

Date Range: 485 weeks

485 weeks ago from today was 30 Dec 2015, a Wednesday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2025. It looks like 485 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 3395 days on a calendar until getting my solution of Wednesday December 30, 2015.

How we calculated 485 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 485 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 16 Apr, then set the calculation - 485 weeks, and factored in the year 2025
  2. Noted your current time of year: 485 weeks in April will bring us back to March or further.
  3. Counted backwards weeks from current day: date - 16 Apr, factoring in the 16 days left in April to calculate Wednesday December 30, 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 30

  • Current date: 16 Apr
  • Day of the week: Wednesday
  • New Date: Wednesday December 30, 2015
  • New Date Day of the week: Wednesday
  • 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 485 weeks ago

  1. Calculate it: Start with a time ago calculator. 485 weeks is easiest solved on a calculator. For ours, we've already factored in the 16 days in April + 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 April's calendar: Begin by identifying 16 Apr on a calendar, note that it’s Wednesday, and the total days in March (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 485 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()-485 to get or =WORKDAY(TODAY()), -485, cell:cell) for working weeks.

Working weeks in 485 calendar weeks

485 weeks is Wednesday December 30, 2015 or could be if you only want workdays. This calculation takes 485 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Wednesday December 30, 2015 date.
