What was the date 40 weeks ago?

Solution

Tuesday August 15, 2023

0

40 weeks ago from today was 15 Aug 2023, a Tuesday. We’re now subtracting quarters of the year. This means 40 weeks from 21 May changes fiscal calendars and could even push us into previous years. We’re currently in end of May with 21 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 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:

  1. We started with date inputs: used current day of 21 May, then set the calculation - 40 weeks, and factored in the year 2024
  2. Noted your current time of year: 40 weeks in May will bring us back to April or further.
  3. Counted backwards weeks from current day: date - 21 May, factoring in the 21 days left in May to calculate Tuesday August 15, 2023
  4. 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 15

  • Current date: 21 May
  • Day of the week: Tuesday
  • New Date: Tuesday August 15, 2023
  • New Date Day of the week: Tuesday
  • 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 40 weeks ago

  1. Calculate it: Start with a time ago calculator. 40 weeks is easiest solved on a calculator. For ours, we've already factored in the 21 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!).
  2. Use May's calendar: Begin by identifying 21 May on a calendar, note that it’s Tuesday, 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 40 times weeks by weeks, subtracting weeks from until your remainder of weeks is 0.
  3. 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 Tuesday August 15, 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 Tuesday August 15, 2023 date.
