How we calculated 820 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 820 days ago gets calculated on each visit:

  1. We started with date inputs: used current day of 28 Mar, then set the calculation - 820 days, and factored in the year 2025
  2. Noted your current time of year: 820 days in March will bring us back to February or further.
  3. Counted backwards days from current day: date - 28 Mar, factoring in the 28 days left in March to calculate Thursday December 29, 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 29

  • Current date: 28 Mar
  • Day of the week: Thursday
  • New Date: Thursday December 29, 2022
  • New Date Day of the week: Thursday
  • 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 820 days ago

  1. Calculate it: Start with a time ago calculator. 820 days is easiest solved on a calculator. For ours, we've already factored in the 28 days in March + 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 March's calendar: Begin by identifying 28 Mar on a calendar, note that it’s Thursday, and the total days in February (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 820 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()-820 to get or =WORKDAY(TODAY()), -820, cell:cell) for working days.

Working days in 820 calendar days

820 days is Thursday December 29, 2022 or could be if you only want workdays. This calculation takes 820 days and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Thursday December 29, 2022 date.
