What was the date 12 months ago?

Solution

Saturday March 16, 2024

0

12 months before today was 16 Mar 2024, a Saturday. Subtracting 12 months in the past is usually just counting from March; however, longer calculations will push us from 2025 into 2024 or further. Even if the calculation remains within the year, I usually take note of the 16 days left in the middle of March to prep for an additional calculation before February. But that’s all there is to it - understand the month, if 12 months will change the year, season, or fiscal calendar, and subtract your dates.

How we calculated 12 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 12 months ago gets calculated on each visit:

  1. We started with date inputs: used current day of 16 Mar, then set the calculation - 12 months, and factored in the year 2025
  2. Noted your current time of year: 12 months in March will keep us in March and we don’t need to worry about adjusting months or years.
  3. Counted backwards months from current day: date - 16 Mar, factoring in the 16 days left in March to calculate Saturday March 16, 2024
  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 March 16

  • Current date: 16 Mar
  • Day of the week: Saturday
  • New Date: Saturday March 16, 2024
  • New Date Day of the week: Saturday
  • March is usually not, but sometimes super tricky. Factor in Leap Years and Easter, which falls on varying dates each year, if you need a date in the past.
  • 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 12 months ago

  1. Calculate it: Start with a time ago calculator. 12 months is easiest solved on a calculator. For ours, we've already factored in the 16 days in March + 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 March's calendar: Begin by identifying 16 Mar on a calendar, note that it’s Saturday, and the total days in February (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 12 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()-12 to get or =WORKDAY(TODAY()), -12, cell:cell) for working months.

Working months in 12 calendar months

12 months is Saturday March 16, 2024 or could be if you only want workdays. This calculation takes 12 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 March 16, 2024 date.
