What was the date 109 months ago?


Tuesday June 16, 2015


109 months before today was 16 Jun 2015, a Tuesday. Subtracting 109 months in the past is usually just counting from July; 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 16 days left in the middle of July to prep for an additional calculation before June. 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 16 Jul, then set the calculation - 109 months, and factored in the year 2024
  2. Noted your current time of year: 109 months in July will bring us back to June or further.
  3. Counted backwards months from current day: date - 16 Jul, factoring in the 16 days left in July to calculate Tuesday June 16, 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 June 16

  • Current date: 16 Jul
  • Day of the week: Tuesday
  • New Date: Tuesday June 16, 2015
  • New Date Day of the week: Tuesday
  • June is the beginning of summer so be careful, counting backwards could put you in the chilly months of spring and winter.
  • 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 16 days in July + 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 July's calendar: Begin by identifying 16 Jul on a calendar, note that it’s Tuesday, and the total days in June (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 Tuesday June 16, 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 Tuesday June 16, 2015 date.
