Solution

Thursday June 30, 2039

Date Range: 171 months

171 months from today is 30 Jun 2039, a Thursday. Adding 171 months in the future is usually just counting from March; however, longer calculations will push us from 2025 into 2026. Even if the calculation remains within the year, I usually take note of the 0 days left in the end of March, to prep for left over days or weeks in the calculation.

Ways to calculate 171 months from today

Just calculate it: Start with a time from today calculator. 171 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 March's calendar: Begin by identifying on a calendar, note that it’s Thursday, and the total days in April (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 171 times by months, adding months from 31 Mar.
Use Excel: Regardless of unit type, I use day calculations here. Type =TODAY()+171 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 171 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.
