659 months from today is 26 Oct 2079, a Thursday. Adding 659 months in the future is usually just counting from November; however, longer calculations will push us from 2024 into 2025. Even if the calculation remains within the year, I usually take note of the 4 days left in the end of November, 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 659 months to today's date gets calculated on each visit:
Thursday Thursday October 26, 2079 is the 299 day of the year or 81.92% through 2079.
659 months is Thursday October 26, 2079 or could be Saturday March 17, 2103 if you only want workdays. This calculation takes 659 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 26, 2079 date.
