How we calculated 509 days 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 509 days ago gets calculated on each visit:

  1. We started with date inputs: used current day of 15 Mar, then set the calculation - 509 days, and factored in the year 2025
  2. Noted your current time of year: 509 days in March will bring us back to February or further.
  3. Counted backwards days from current day: date - 15 Mar, factoring in the 15 days left in March to calculate Monday October 23, 2023
  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 23

  • Current date: 15 Mar
  • Day of the week: Monday
  • New Date: Monday October 23, 2023
  • New Date Day of the week: Monday
  • 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 509 days ago

  1. Calculate it: Start with a time ago calculator. 509 days is easiest solved on a calculator. For ours, we've already factored in the 15 days in March + all number of days in each month and the number of days in . Simply add your days 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 15 Mar on a calendar, note that it’s Monday, 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 509 times days by days, subtracting days from until your remainder of days is 0.
  3. Use excel: For more complex days calculations or if you h8 our site (kidding), I use Excel functions like =TODAY()-509 to get or =WORKDAY(TODAY()), -509, cell:cell) for working days.

Working days in 509 calendar days

509 days is Monday October 23, 2023 or could be if you only want workdays. This calculation takes 509 days and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Monday October 23, 2023 date.
