What was the date 600 months ago?

Solution

Monday November 25, 1974

0

600 months before today was 25 Nov 1974, a Monday. Subtracting 600 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 600 months will change the year, season, or fiscal calendar, and subtract your dates.

How we calculated 600 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 600 months ago gets calculated on each visit:

We started with date inputs: used current day of 25 Nov, then set the calculation - 600 months, and factored in the year 2024
Noted your current time of year: 600 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 Monday November 25, 1974
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

Current date: 25 Nov
Day of the week: Monday
New Date: Monday November 25, 1974
New Date Day of the week: Monday
In Novemeber, account for the end of the year holidays when counting backwards.
The solution crosses into a different year.

Ways to calculate 600 months ago

Calculate it: Start with a time ago calculator. 600 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 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 600 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()-600 to get or =WORKDAY(TODAY()), -600, cell:cell) for working months.

Working months in 600 calendar months

600 months is Monday November 25, 1974 or could be if you only want workdays. This calculation takes 600 months and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Monday November 25, 1974 date.
