489 weeks ago from today was 29 Feb 2016, a Monday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2025. It looks like 489 weeks from now will bring us back to pre 2024 and we’ll need to factor this into our subtraction because it will change the calendar and fiscal years. For larger calculations like this, I start by subtracting total days, then counting backwards 3423 days on a calendar until getting my solution of Monday February 29, 2016.

How we calculated 489 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 489 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 14 Jul, then set the calculation - 489 weeks, and factored in the year 2025
  2. Noted your current time of year: 489 weeks in July will bring us back to June or further.
  3. Counted backwards weeks from current day: date - 14 Jul, factoring in the 14 days left in July to calculate Monday February 29, 2016
  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 29

  • Current date: 14 Jul
  • Day of the week: Monday
  • New Date: Monday February 29, 2016
  • New Date Day of the week: Monday
  • 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.
  • The solution crosses into a different year.

Ways to calculate 489 weeks ago

  1. Calculate it: Start with a time ago calculator. 489 weeks is easiest solved on a calculator. For ours, we've already factored in the 14 days in July + 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 July's calendar: Begin by identifying 14 Jul on a calendar, note that it’s Monday, and the total days in June (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 489 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()-489 to get or =WORKDAY(TODAY()), -489, cell:cell) for working weeks.

Working weeks in 489 calendar weeks

489 weeks is Monday February 29, 2016 or could be if you only want workdays. This calculation takes 489 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 February 29, 2016 date.
