991 months from today is 26 Sep 2107, a Monday. Adding 991 months in the future is usually just counting from February; however, longer calculations will push us from 2025 into 2026. Even if the calculation remains within the year, I usually take note of the 2 days left in the end of February, to prep for left over days or weeks in the calculation.

Ways to calculate 991 months from today

Just calculate it: Start with a time from today calculator. 991 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 February's calendar: Begin by identifying on a calendar, note that it’s Monday, and the total days in March (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 991 times by months, adding months from 26 Feb.
Use Excel: Regardless of unit type, I use day calculations here. Type =TODAY()+991 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 991 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.

991 months is Monday September 26, 2107 or could be Thursday November 29, 2142 if you only want workdays. This calculation takes 991 months and only adds by the number of workdays in a week.
