18 months from today is 23 Nov 2026, a Monday. Adding 18 months in the future is usually just counting from May; however, longer calculations will push us from 2025 into 2026. Even if the calculation remains within the year, I usually take note of the 8 days left in the end of May, to prep for left over days or weeks in the calculation.

How we calculated 18 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 18 months to today's date gets calculated on each visit:

Started with date inputs: starting point: 23 May, Units to add: 18 months, and year: 2025
Noted your current time of year: 8 days in end of May
Added 18 months from current day: 23 May, factoring in there are 8 days left in before June
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: November 23

Monday Monday November 23, 2026 is the 327 day of the year or 89.59% through 2026.

Ways to calculate 18 months from today

Just calculate it: Start with a time from today calculator. 18 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 May's calendar: Begin by identifying on a calendar, note that it’s Monday, 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 18 times by months, adding months from 23 May.
Use Excel: Regardless of unit type, I use day calculations here. Type =TODAY()+18 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 18 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.

18 working months from today

18 months is Monday November 23, 2026 or could be Monday July 12, 2027 if you only want workdays. This calculation takes 18 months and only adds by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Monday November 23, 2026 date.
