504 months before today was 25 Nov 1982, a Thursday. Subtracting 504 months in the past is usually just counting from November; however, longer calculations will push us from 2024 into 2023 or further. Even if the calculation remains within the year, I usually take note of the 25 days left in the end of November to prep for an additional calculation before October. But that’s all there is to it - understand the month, if 504 months will change the year, season, or fiscal calendar, and subtract your dates.

How we calculated 504 months 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 504 months ago gets calculated on each visit:

We started with date inputs: used current day of 25 Nov, then set the calculation - 504 months, and factored in the year 2024
Noted your current time of year: 504 months in November will bring us back to October or further.
Counted backwards months from current day: date - 25 Nov, factoring in the 25 days left in November to calculate Thursday November 25, 1982
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 25

The solution crosses into a different year.

Ways to calculate 504 months ago

Calculate it: Start with a time ago calculator. 504 months 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 months and choose the length of time, then click "calculate". This calculation does not factor in workdays or holidays (see below!).
Use November's calendar: Begin by identifying 25 Nov on a calendar, note that it’s Thursday, 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 504 times months by months, subtracting months from until your remainder of months is 0.
Use excel: For more complex months calculations or if you h8 our site (kidding), I use Excel functions like =TODAY()-504 to get or =WORKDAY(TODAY()), -504, cell:cell) for working months.
