640 months from today is 29 Mar 2078, a Tuesday. Adding 640 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 1 days left in the end of November, to prep for left over days or weeks in the calculation.

Ways to calculate 640 months from today

Just calculate it: Start with a time from today calculator. 640 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 November's calendar: Begin by identifying on a calendar, note that it’s Tuesday, and the total days in December (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 640 times by months, adding months from 29 Nov.
Use Excel: Regardless of unit type, I use day calculations here. Type =TODAY()+640 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 640 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.

640 months is Tuesday March 29, 2078 or could be Friday December 17, 2100 if you only want workdays. This calculation takes 640 months and only adds by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Tuesday March 29, 2078 date.
