What was the date 40 weeks ago?

Solution

Friday July 21, 2023

40 weeks ago from today was 21 Jul 2023, a Friday. We’re now subtracting quarters of the year. This means 40 weeks from 26 Apr changes fiscal calendars and could even push us into previous years. We’re currently in end of April with 9 days left. This will bring us back to March or further.. When I calculate backwards for larger weeks before today, start with subtracting the days, then count backwards to find the correct weeks.

How we calculated 40 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 40 weeks ago gets calculated on each visit:

We started with date inputs: used current day of 26 Apr, then set the calculation - 40 weeks, and factored in the year 2024
Noted your current time of year: 40 weeks in April will bring us back to March or further.
Counted backwards weeks from current day: date - 26 Apr, factoring in the 9 days left in April to calculate Friday July 21, 2023
Did NOT factor in workdays: In this calculation, we kept weekend. See below for just workdays or the fiscal calendar

Tips when solving for July 21

Current date: 26 Apr

July is one of the highest vacation months, so prepare for more OOO messages.
This calculation crosses at least one month. Remeber, this will change our day of the week.
The solution crosses into a different year.
Your date will be a weekend. Consider if you only want workdays in your calculation.

Ways to calculate 40 weeks ago

Calculate it: Start with a time ago calculator. 40 weeks is easiest solved on a calculator. For ours, we've already factored in the 9 days in April + 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 April's calendar: Begin by identifying 26 Apr on a calendar, note that it’s Friday, and the total days in March (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 40 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()-40 to get or =WORKDAY(TODAY()), -40, cell:cell) for working weeks.

Working weeks in 40 calendar weeks

40 weeks is Friday July 21, 2023 or could be if you only want workdays. This calculation takes 40 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Friday July 21, 2023 date.
