What was the date 15 weeks ago?

Solution

Wednesday October 16, 2024

0

15 weeks ago from today was 16 Oct 2024, a Wednesday. We’re now subtracting quarters of the year. This means 15 weeks from 29 Jan changes fiscal calendars and could even push us into previous years. We’re currently in end of January with 29 days left; this will keep us in January and we don’t need to worry about adjusting months or years. 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 15 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 15 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 29 Jan, then set the calculation - 15 weeks, and factored in the year 2025
  2. Noted your current time of year: 15 weeks in January will keep us in January and we don’t need to worry about adjusting months or years.
  3. Counted backwards weeks from current day: date - 29 Jan, factoring in the 29 days left in January to calculate Wednesday October 16, 2024
  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 October 16

  • Current date: 29 Jan
  • Day of the week: Wednesday
  • New Date: Wednesday October 16, 2024
  • New Date Day of the week: Wednesday
  • October marks the start of Q4 so counting backward will put you back into the 3 fiscal quarter.
  • 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 15 weeks ago

  1. Calculate it: Start with a time ago calculator. 15 weeks is easiest solved on a calculator. For ours, we've already factored in the 29 days in January + 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 January's calendar: Begin by identifying 29 Jan on a calendar, note that it’s Wednesday, and the total days in (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 15 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()-15 to get or =WORKDAY(TODAY()), -15, cell:cell) for working weeks.

Working weeks in 15 calendar weeks

15 weeks is Wednesday October 16, 2024 or could be if you only want workdays. This calculation takes 15 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Wednesday October 16, 2024 date.
