What was the date 505 months ago?

Solution

Saturday April 10, 1982

0

505 months before today was 10 Apr 1982, a Saturday. Subtracting 505 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 10 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 505 months will change the year, season, or fiscal calendar, and subtract your dates.

How we calculated 505 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 505 months ago gets calculated on each visit:

  1. We started with date inputs: used current day of 10 May, then set the calculation - 505 months, and factored in the year 2024
  2. Noted your current time of year: 505 months in May will bring us back to April or further.
  3. Counted backwards months from current day: date - 10 May, factoring in the 10 days left in May to calculate Saturday April 10, 1982
  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 April 10

  • Current date: 10 May
  • Day of the week: Saturday
  • New Date: Saturday April 10, 1982
  • New Date Day of the week: Saturday
  • April is the end of the quarter and the beginning of spring. It's also Phillies Opening Day, so plan according and take the week off work! (Go Phils)
  • 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 505 months ago

  1. Calculate it: Start with a time ago calculator. 505 months is easiest solved on a calculator. For ours, we've already factored in the 10 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 10 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 505 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()-505 to get or =WORKDAY(TODAY()), -505, cell:cell) for working months.

Working months in 505 calendar months

505 months is Saturday April 10, 1982 or could be if you only want workdays. This calculation takes 505 months and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Saturday April 10, 1982 date.
