What was the date 518 months ago?

Solution

Thursday March 12, 1981

0

518 months before today was 12 Mar 1981, a Thursday. Subtracting 518 months in the past is usually just counting from May; 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 12 days left in the middle of May to prep for an additional calculation before April. But that’s all there is to it - understand the month, if 518 months will change the year, season, or fiscal calendar, and subtract your dates.

How we calculated 518 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 518 months ago gets calculated on each visit:

  1. We started with date inputs: used current day of 12 May, then set the calculation - 518 months, and factored in the year 2024
  2. Noted your current time of year: 518 months in May will bring us back to April or further.
  3. Counted backwards months from current day: date - 12 May, factoring in the 12 days left in May to calculate Thursday March 12, 1981
  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 12

  • Current date: 12 May
  • Day of the week: Thursday
  • New Date: Thursday March 12, 1981
  • 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 518 months ago

  1. Calculate it: Start with a time ago calculator. 518 months is easiest solved on a calculator. For ours, we've already factored in the 12 days in May + 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 May's calendar: Begin by identifying 12 May on a calendar, note that it’s Thursday, 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 518 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()-518 to get or =WORKDAY(TODAY()), -518, cell:cell) for working months.

518 months is Thursday March 12, 1981 or could be if you only want workdays. This calculation takes 518 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 12, 1981 date.
