What was the date 18 weeks ago?

Solution

Thursday November 21, 2024

Date Range: 18 weeks

18 weeks ago from today was 21 Nov 2024, a Thursday. We’re now subtracting quarters of the year. This means 18 weeks from 27 Mar changes fiscal calendars and could even push us into previous years. We’re currently in end of March with 27 days left; this will keep us in March 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 18 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 18 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 27 Mar, then set the calculation - 18 weeks, and factored in the year 2025
  2. Noted your current time of year: 18 weeks in March will keep us in March and we don’t need to worry about adjusting months or years.
  3. Counted backwards weeks from current day: date - 27 Mar, factoring in the 27 days left in March to calculate Thursday November 21, 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 November 21

  • Current date: 27 Mar
  • Day of the week: Thursday
  • New Date: Thursday November 21, 2024
  • New Date Day of the week: Thursday
  • In Novemeber, account for the end of the year holidays when counting backwards.
  • 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 18 weeks ago

  1. Calculate it: Start with a time ago calculator. 18 weeks is easiest solved on a calculator. For ours, we've already factored in the 27 days in March + 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 March's calendar: Begin by identifying 27 Mar on a calendar, note that it’s Thursday, and the total days in February (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 18 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()-18 to get or =WORKDAY(TODAY()), -18, cell:cell) for working weeks.

Working weeks in 18 calendar weeks

18 weeks is Thursday November 21, 2024 or could be if you only want workdays. This calculation takes 18 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Thursday November 21, 2024 date.
