666 months from today is 18 Aug 2080, a Sunday. Adding 666 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 10 days left in the middle of February, to prep for left over days or weeks in the calculation.

How we calculated 666 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 666 months to today's date gets calculated on each visit:

Ways to calculate 666 months from today

Just calculate it: Start with a time from today calculator. 666 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 Sunday, 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 666 times by months, adding months from 18 Feb.
Use Excel: Regardless of unit type, I use day calculations here. Type =TODAY()+666 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 666 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.

666 months is Sunday August 18, 2080 or could be Wednesday April 09, 2104 if you only want workdays. This calculation takes 666 months and only adds by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Sunday August 18, 2080 date.
