How we calculated 138 weeks 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 138 weeks to today's date gets calculated on each visit:

Started with date inputs: starting point: 29 Apr, Units to add: 138 weeks, and year: 2024
Noted your current time of year: 138 weeks in end of April will bring us into May. (Or far beyond).
Added 138 weeks from current day: 29 Apr, factoring in there are 9 weeks left in before May
Did NOT factor in workdays: In this calculation, we kept weekend. See below for just workdays or the 2024 fiscal calendar.

Monday Monday December 21, 2026 is the 355 day of the year or 97.26% through 2026.

Ways to calculate 138 weeks from today

Just calculate it: Start with a time from today calculator. 138 weeks 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 weeks and choose the length of time, then click "calculate". This calculation does not factor in workdays or holidays (see below!).
Use April's calendar: Begin by identifying on a calendar, note that it’s Monday, and the total days in May (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 138 times by weeks, adding weeks from 29 Apr.
Use Excel: Regardless of unit type, I use day calculations here. Type =TODAY()+138 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 138 weeks 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.

138 weeks is Monday December 21, 2026 or could be Tuesday January 11, 2028 if you only want workdays. This calculation takes 138 weeks and only adds by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Monday December 21, 2026 date.
