15 months from today is 15 Oct 2026, a Thursday. Adding 15 months in the future is usually just counting from July; however, longer calculations will push us from 2025 into 2026. Even if the calculation remains within the year, I usually take note of the 16 days left in the middle of July, 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: 15 Jul, Units to add: 15 months, and year: 2025
Noted your current time of year: 16 days in middle of July
Added 15 months from current day: 15 Jul, factoring in there are 16 days left in before August
Did NOT factor in workdays: In this calculation, we kept weekend. See below for just workdays or the 2025 fiscal calendar.

Tips to get your solution: October 15

Thursday Thursday October 15, 2026 is the 288 day of the year or 78.9% through 2026.

Counting dates from July might put you in the fall. Remember, July is a big vacation month so you might need to factor in vacation time in your calculation.
This calculation crosses at least one month. Remeber, this will change our day of the week.

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 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!).
Use July's calendar: Begin by identifying on a calendar, note that it’s Thursday, and the total days in August (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 15 Jul.
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 Thursday October 15, 2026 or could be Tuesday April 27, 2027 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 Thursday October 15, 2026 date.
