505 weeks ago from today was 23 Mar 2015, a Monday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 505 weeks from now will bring us back to pre 2023 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 3535 days on a calendar until getting my solution of Monday March 23, 2015.

How we calculated 505 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 505 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 25 Nov, then set the calculation - 505 weeks, and factored in the year 2024
  2. Noted your current time of year: 505 weeks in November will bring us back to October or further.
  3. Counted backwards weeks from current day: date - 25 Nov, factoring in the 25 days left in November to calculate Monday March 23, 2015
  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 March 23

  • Current date: 25 Nov
  • Day of the week: Monday
  • New Date: Monday March 23, 2015
  • New Date Day of the week: Monday
  • March is usually not, but sometimes super tricky. Factor in Leap Years and Easter, which falls on varying dates each year, if you need a date in the past.
  • 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 505 weeks ago

  1. Calculate it: Start with a time ago calculator. 505 weeks is easiest solved on a calculator. For ours, we've already factored in the 25 days in November + 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 November's calendar: Begin by identifying 25 Nov on a calendar, note that it’s Monday, and the total days in October (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 505 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()-505 to get or =WORKDAY(TODAY()), -505, cell:cell) for working weeks.

Working weeks in 505 calendar weeks

505 weeks is Monday March 23, 2015 or could be if you only want workdays. This calculation takes 505 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 March 23, 2015 date.
