How we calculated 520 days 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 520 days ago gets calculated on each visit:

  1. We started with date inputs: used current day of 13 May, then set the calculation - 520 days, and factored in the year 2024
  2. Noted your current time of year: 520 days in May will bring us back to April or further.
  3. Counted backwards days from current day: date - 13 May, factoring in the 13 days left in May to calculate Saturday December 10, 2022
  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 10

  • Current date: 13 May
  • Day of the week: Saturday
  • New Date: Saturday December 10, 2022
  • 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 520 days ago

  1. Calculate it: Start with a time ago calculator. 520 days is easiest solved on a calculator. For ours, we've already factored in the 13 days in May + all number of days in each month and the number of days in . Simply add your days and choose the length of time, then click "calculate". This calculation does not factor in workdays or holidays (see below!).
  2. Use May's calendar: Begin by identifying 13 May on a calendar, note that it’s Saturday, and the total days in April (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 520 times days by days, subtracting days from until your remainder of days is 0.
  3. Use excel: For more complex days calculations or if you h8 our site (kidding), I use Excel functions like =TODAY()-520 to get or =WORKDAY(TODAY()), -520, cell:cell) for working days.

Working days in 520 calendar days

520 days is Saturday December 10, 2022 or could be if you only want workdays. This calculation takes 520 days 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 10, 2022 date.
