What was the date 15 weeks ago?


Wednesday February 14, 2024


15 weeks ago from today was 14 Feb 2024, a Wednesday. We’re now subtracting quarters of the year. This means 15 weeks from 29 May changes fiscal calendars and could even push us into previous years. We’re currently in end of May with 29 days left; this will keep us in May 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 May, then set the calculation - 15 weeks, and factored in the year 2024
  2. Noted your current time of year: 15 weeks in May will keep us in May and we don’t need to worry about adjusting months or years.
  3. Counted backwards weeks from current day: date - 29 May, factoring in the 29 days left in May to calculate Wednesday February 14, 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 February 14

  • Current date: 29 May
  • Day of the week: Wednesday
  • New Date: Wednesday February 14, 2024
  • New Date Day of the week: Wednesday
  • Remember February has 28 or 29 days depending on Leap Year! This may not impact time in the past, but it will impact future dates.
  • This calculation crosses at least one month. Remeber, this will change our day of the week.

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 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 29 May on a calendar, note that it’s Wednesday, 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 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 February 14, 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 February 14, 2024 date.
