39 weeks ago from today was 21 Aug 2023, a Monday. We’re now subtracting quarters of the year. This means 39 weeks from 20 May changes fiscal calendars and could even push us into previous years. We’re currently in middle of May with 20 days left; this will bring us back to April or further. When I calculate backwards for larger weeks before today, I like to start by subtracting the days, then count backwards to find the correct weeks.

How we calculated 39 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 39 weeks ago gets calculated on each visit:

We started with date inputs: used current day of 20 May, then set the calculation - 39 weeks, and factored in the year 2024
Noted your current time of year: 39 weeks in May will bring us back to April or further.
Counted backwards weeks from current day: date - 20 May, factoring in the 20 days left in May to calculate Monday August 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 August 21

Current date: 20 May
Day of the week: Monday
New Date: Monday August 21, 2023
New Date Day of the week: Monday
August is the beginning of Q3. Dates in previous months will be part of 1H fiscal years.
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 39 weeks ago

Calculate it: Start with a time ago calculator. 39 weeks is easiest solved on a calculator. For ours, we've already factored in the 20 days in May + 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 May's calendar: Begin by identifying 20 May 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 last year (double trust me, you'll need this for larger calculations). From there, count backwards 39 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()-39 to get or =WORKDAY(TODAY()), -39, cell:cell) for working weeks.

Working weeks in 39 calendar weeks

39 weeks is Monday August 21, 2023 or could be if you only want workdays. This calculation takes 39 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Monday August 21, 2023 date.
