138 months from today is 20 Sep 2036, a Saturday. Adding 138 months in the future is usually just counting from March; however, longer calculations will push us from 2025 into 2026. Even if the calculation remains within the year, I usually take note of the 11 days left in the middle of March, to prep for left over days or weeks in the calculation.

Ways to calculate 138 months from today

  1. Just calculate it: Start with a time from today calculator. 138 months is easiest solved on a calculator. For ours, we've already factored in the days in + all number of days in each month and the number of days in 2025. 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 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 next year (double trust me, you'll need this for larger calculations). From there, count forward 138 times by months, adding months from 20 Mar.
  3. Use Excel: Regardless of unit type, I use day calculations here. Type =TODAY()+138 into the cell. If you want to add weeks, multiply your day by 7 and months/years will take their own calculation due to the changing days of the week. To find 138 months workdays, convert to days but use =WORKDAY(TODAY(), [number of days], [holidays]) into the cell. [number of days] is how many working days you want to add, and [holidays] is an optional range of cells that contain dates of holidays to exclude.
