What was the date 15 months ago?

Solution

Saturday February 18, 2023

0

15 months before today was 18 Feb 2023, a Saturday. Subtracting 15 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 18 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 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 18 May, then set the calculation - 15 months, and factored in the year 2024
  2. Noted your current time of year: 15 months in May will keep us in May and we don’t need to worry about adjusting months or years.
  3. Counted backwards months from current day: date - 18 May, factoring in the 18 days left in May to calculate Saturday February 18, 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 February 18

  • Current date: 18 May
  • Day of the week: Saturday
  • New Date: Saturday February 18, 2023
  • New Date Day of the week: Saturday
  • Remember February has 28 or 29 days depending on Leap Year! This may not impact time in the past, but it will impact future dates.
  • 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 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 18 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 18 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 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 Saturday February 18, 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 Saturday February 18, 2023 date.
