What was the date 15 months ago?

Solution

Thursday April 27, 2023

0

15 months before today was 27 Apr 2023, a Thursday. Subtracting 15 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 27 days left in the end of July to prep for an additional calculation before June. But that’s all there is to it - understand the month, if 15 months will change the year, season, or fiscal calendar, and subtract your dates.

How we calculated 15 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 15 months ago gets calculated on each visit:

  1. We started with date inputs: used current day of 27 Jul, then set the calculation - 15 months, and factored in the year 2024
  2. Noted your current time of year: 15 months in July will keep us in July and we don’t need to worry about adjusting months or years.
  3. Counted backwards months from current day: date - 27 Jul, factoring in the 27 days left in July to calculate Thursday April 27, 2023
  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 27

  • Current date: 27 Jul
  • Day of the week: Thursday
  • New Date: Thursday April 27, 2023
  • New Date Day of the week: Thursday
  • 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 15 months ago

  1. Calculate it: Start with a time ago calculator. 15 months is easiest solved on a calculator. For ours, we've already factored in the 27 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 27 Jul on a calendar, note that it’s Thursday, 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 15 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()-15 to get or =WORKDAY(TODAY()), -15, cell:cell) for working months.

Working months in 15 calendar months

15 months is Thursday April 27, 2023 or could be if you only want workdays. This calculation takes 15 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 April 27, 2023 date.
