Sunday September 14, 2025

0

8 weeks ago from today was 14 Sep 2025, a Sunday. Week conversions that span across multiple months now must consider the 9 days left in middle of November because 8 weeks will keep us in November and we don’t need to worry about adjusting months or years. Run this calculation first by understanding where we’re at in November, identify if we’ll drop into October, and count backwards by 8.

How we calculated 8 weeks before 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 8 weeks ago gets calculated on each visit:

We started with date inputs: used current day of 09 Nov, then set the calculation - 8 weeks, and factored in the year 2025
Noted your current time of year: 8 weeks in November will keep us in November and we don’t need to worry about adjusting months or years.
Counted backwards weeks from current day: date - 09 Nov, factoring in the 9 days left in November to calculate Sunday September 14, 2025
Did NOT factor in workdays: In this calculation, we kept weekend. See below for just workdays or the fiscal calendar

Tips when solving for September 14

Current date: 09 Nov
Day of the week: Sunday
New Date: Sunday September 14, 2025
New Date Day of the week: Sunday
Counting backward from September puts you back into the summer! September is the official start of fall.
This calculation crosses at least one month. Remeber, this will change our day of the week.

Ways to calculate 8 weeks ago

Calculate it: Start with a time ago calculator. 8 weeks is easiest solved on a calculator. For ours, we've already factored in the 9 days in November + all number of days in each month and the number of days in . 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 November's calendar: Begin by identifying 09 Nov on a calendar, note that it’s Sunday, and the total days in October (trust me, you’ll need this for smaller calculations) and days until last year (double trust me, you'll need this for larger calculations). From there, count backwards 8 times weeks by weeks, subtracting weeks from until your remainder of weeks is 0.
Use excel: For more complex weeks calculations or if you h8 our site (kidding), I use Excel functions like =TODAY()-8 to get or =WORKDAY(TODAY()), -8, cell:cell) for working weeks.

Working weeks in 8 calendar weeks

8 weeks is Sunday September 14, 2025 or could be if you only want workdays. This calculation takes 8 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Sunday September 14, 2025 date.
