What was the date 109 months ago?

Solution

Monday April 20, 2015

0

109 months before today was 20 Apr 2015, a Monday. Subtracting 109 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 20 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 109 months will change the year, season, or fiscal calendar, and subtract your dates.

How we calculated 109 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 109 months ago gets calculated on each visit:

  1. We started with date inputs: used current day of 20 May, then set the calculation - 109 months, and factored in the year 2024
  2. Noted your current time of year: 109 months in May will bring us back to April or further.
  3. Counted backwards months from current day: date - 20 May, factoring in the 20 days left in May to calculate Monday April 20, 2015
  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 20

  • Current date: 20 May
  • Day of the week: Monday
  • New Date: Monday April 20, 2015
  • New Date Day of the week: Monday
  • 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.

Ways to calculate 109 months ago

  1. Calculate it: Start with a time ago calculator. 109 months is easiest solved on a calculator. For ours, we've already factored in the 20 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 20 May on a calendar, note that it’s Monday, 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 109 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()-109 to get or =WORKDAY(TODAY()), -109, cell:cell) for working months.

Working months in 109 calendar months

109 months is Monday April 20, 2015 or could be if you only want workdays. This calculation takes 109 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 April 20, 2015 date.
