What was the date 18 months ago?


Saturday December 24, 2022


18 months before today was 24 Dec 2022, a Saturday. Subtracting 18 months in the past is usually just counting from June; 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 24 days left in the end of June to prep for an additional calculation before May. But that’s all there is to it - understand the month, if 18 months will change the year, season, or fiscal calendar, and subtract your dates.

How we calculated 18 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 18 months ago gets calculated on each visit:

  1. We started with date inputs: used current day of 24 Jun, then set the calculation - 18 months, and factored in the year 2024
  2. Noted your current time of year: 18 months in June will keep us in June and we don’t need to worry about adjusting months or years.
  3. Counted backwards months from current day: date - 24 Jun, factoring in the 24 days left in June to calculate Saturday December 24, 2022
  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 December 24

  • Current date: 24 Jun
  • Day of the week: Saturday
  • New Date: Saturday December 24, 2022
  • New Date Day of the week: Saturday
  • December marks the end of the year, so account for all the out of office notifications when counting backwards.
  • 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 18 months ago

  1. Calculate it: Start with a time ago calculator. 18 months is easiest solved on a calculator. For ours, we've already factored in the 24 days in June + 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 June's calendar: Begin by identifying 24 Jun on a calendar, note that it’s Saturday, and the total days in May (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 18 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()-18 to get or =WORKDAY(TODAY()), -18, cell:cell) for working months.

Working months in 18 calendar months

18 months is Saturday December 24, 2022 or could be if you only want workdays. This calculation takes 18 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 December 24, 2022 date.
