(Max(StartA, StartB) <= Min(EndA, EndB), But to implement Min() and Max(), you have to code, (using C ternary for terseness),: How to test whether two time ranges overlap? index.js A ternary operator is the most performant method by far. You assume that we are talking about asp, which is not necessarily right. Lets see what the minimum and maximum are: You are correct, while your code gives a minimum value that you may be able to use as minimum, the max value that it gives is about as far off as can be. This automatically accounts for leap year. 15 goes like this: [before:before, start, within, end, after], [start:start, within, end, after],[within:within, end, after], [end:end, after], [after:after]. For example, I have the dates in column AC and stock prices in column AG. If there are roughly 2510 rows in 10 years, round up to a number guaranteed to include the 10 years, say 2600 rows. For example, from "02/15/2020" to "04/02/2020" is 47 days. In the formula, the "y" returns the number of full years between the two days. How to get an enum value from a string value in Java.
