What's the date 18 weeks from today?

Solution

Thursday August 14, 2025

Date Range: 18 weeks

18 weeks from today will be 14 Aug 2025, a Thursday. Looking forward by quarters of the year means 18 weeks from today changes fiscal calendars and might even carry us into the next year. Currently in the middle of of April with 30 days in the month, I would first count the days to May - you'll need this for your calendar, then multiple 18 by days to get 126. Then I'll be able to count 126 days from May until getting to Thursday August 14, 2025.

How we calculated 18 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 18 weeks to today's date gets calculated on each visit:

Started with date inputs: starting point: 10 Apr, Units to add: 18 weeks, and year: 2025
Noted your current time of year: 20 days in middle of April
Added 18 weeks from current day: 10 Apr, factoring in there are 20 days left in before May
Did NOT factor in workdays: In this calculation, we kept weekend. See below for just workdays or the 2025 fiscal calendar.

Ways to calculate 18 weeks from today

Just calculate it: Start with a time from today calculator. 18 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 2025. 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 Thursday, 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 18 times by weeks, adding weeks from 10 Apr.
Use Excel: Regardless of unit type, I use day calculations here. Type =TODAY()+18 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 18 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.

18 working weeks from today

18 weeks is Thursday August 14, 2025 or could be Friday October 03, 2025 if you only want workdays. This calculation takes 18 weeks and only adds by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Thursday August 14, 2025 date.
