What was the date 500 months ago?

Solution

Monday March 28, 1983

0

500 months before today was 28 Mar 1983, a Monday. Subtracting 500 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 28 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 500 months will change the year, season, or fiscal calendar, and subtract your dates.

How we calculated 500 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 500 months ago gets calculated on each visit:

  1. We started with date inputs: used current day of 28 Nov, then set the calculation - 500 months, and factored in the year 2024
  2. Noted your current time of year: 500 months in November will bring us back to October or further.
  3. Counted backwards months from current day: date - 28 Nov, factoring in the 28 days left in November to calculate Monday March 28, 1983
  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 28

  • Current date: 28 Nov
  • Day of the week: Monday
  • New Date: Monday March 28, 1983
  • New Date Day of the week: Monday
  • 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 500 months ago

  1. Calculate it: Start with a time ago calculator. 500 months is easiest solved on a calculator. For ours, we've already factored in the 28 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 28 Nov on a calendar, note that it’s Monday, 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 500 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()-500 to get or =WORKDAY(TODAY()), -500, cell:cell) for working months.

Working months in 500 calendar months

500 months is Monday March 28, 1983 or could be if you only want workdays. This calculation takes 500 months and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Monday March 28, 1983 date.
