18 months from today is 20 Nov 2025, a Thursday. Adding 18 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.
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:
Thursday Thursday November 20, 2025 is the 324 day of the year or 88.77% through 2025.
18 months is Thursday November 20, 2025 or could be Thursday July 09, 2026 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 Thursday November 20, 2025 date.
