15 months from today is 20 Aug 2025, a Wednesday. Adding 15 months in the future is usually just counting from May; however, longer calculations will push us from 2024 into 2025. Even if the calculation remains within the year, I usually take note of the 11 days left in the middle of May, to prep for left over days or weeks in the calculation.

How we calculated 15 months from 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 adding 15 months to today's date gets calculated on each visit:

Started with date inputs: starting point: 20 May, Units to add: 15 months, and year: 2024
Noted your current time of year: 11 days in middle of May
Added 15 months from current day: 20 May, factoring in there are 11 days left in before June
Did NOT factor in workdays: In this calculation, we kept weekend. See below for just workdays or the 2024 fiscal calendar.

Tips to get your solution: August 20

Wednesday Wednesday August 20, 2025 is the 232 day of the year or 63.56% through 2025.

Ways to calculate 15 months from today

Just calculate it: Start with a time from today calculator. 15 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 2024. Simply add your months and choose the length of time, then click "calculate". This calculation does not factor in workdays or holidays (see below!).
Use May's calendar: Begin by identifying on a calendar, note that it’s Wednesday, and the total days in June (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 15 times by months, adding months from 20 May.
Use Excel: Regardless of unit type, I use day calculations here. Type =TODAY()+15 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 15 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.

15 working months from today

15 months is Wednesday August 20, 2025 or could be Monday March 02, 2026 if you only want workdays. This calculation takes 15 months and only adds by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Wednesday August 20, 2025 date.
