40 months from today is 17 Jul 2028, a Monday. Adding 40 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 14 days left in the middle of March, to prep for left over days or weeks in the calculation.

How we calculated 40 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 40 months to today's date gets calculated on each visit:

Started with date inputs: starting point: 17 Mar, Units to add: 40 months, and year: 2025
Noted your current time of year: 14 days in middle of March
Added 40 months from current day: 17 Mar, factoring in there are 14 days left in before April
Did NOT factor in workdays: In this calculation, we kept weekend. See below for just workdays or the 2025 fiscal calendar.

Tips to get your solution: July 17

Monday Monday July 17, 2028 is the 199 day of the year or 54.52% through 2028.

Current date: 17 Mar
Day of the week: Monday
New Date: Monday July 17, 2028
New Date Day of the week: Monday
Factor in Easter which can fall in March some years, plus it's the end of Q1. Counting forward from here could put you into a new fiscal quarter.
This calculation crosses at least one month. Remeber, this will change our day of the week.
The solution crosses into a different year..

Ways to calculate 40 months from today

Just calculate it: Start with a time from today calculator. 40 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 Monday, 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 40 times by months, adding months from 17 Mar.
Use Excel: Regardless of unit type, I use day calculations here. Type =TODAY()+40 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 40 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.

40 working months from today

40 months is Monday July 17, 2028 or could be Monday December 17, 2029 if you only want workdays. This calculation takes 40 months and only adds by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Monday July 17, 2028 date.
