What was the date 620 months ago?

Solution

Thursday March 29, 1973

0

620 months before today was 29 Mar 1973, a Thursday. Subtracting 620 months in the past is usually just counting from November; however, longer calculations will push us from 2024 into 2023 or further. Even if the calculation remains within the year, I usually take note of the 29 days left in the end of November to prep for an additional calculation before October. But that’s all there is to it - understand the month, if 620 months will change the year, season, or fiscal calendar, and subtract your dates.

How we calculated 620 months 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 620 months ago gets calculated on each visit:

  1. We started with date inputs: used current day of 29 Nov, then set the calculation - 620 months, and factored in the year 2024
  2. Noted your current time of year: 620 months in November will bring us back to October or further.
  3. Counted backwards months from current day: date - 29 Nov, factoring in the 29 days left in November to calculate Thursday March 29, 1973
  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 March 29

  • Current date: 29 Nov
  • Day of the week: Thursday
  • New Date: Thursday March 29, 1973
  • New Date Day of the week: Thursday
  • March is usually not, but sometimes super tricky. Factor in Leap Years and Easter, which falls on varying dates each year, if you need a date in the past.
  • 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 620 months ago

  1. Calculate it: Start with a time ago calculator. 620 months is easiest solved on a calculator. For ours, we've already factored in the 29 days in November + all number of days in each month and the number of days in . Simply add your months 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 29 Nov on a calendar, note that it’s Thursday, 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 620 times months by months, subtracting months from until your remainder of months is 0.
  3. Use excel: For more complex months calculations or if you h8 our site (kidding), I use Excel functions like =TODAY()-620 to get or =WORKDAY(TODAY()), -620, cell:cell) for working months.

Working months in 620 calendar months

620 months is Thursday March 29, 1973 or could be if you only want workdays. This calculation takes 620 months and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Thursday March 29, 1973 date.
