How do I know how many weekdays of specific types (for example, only Mondays, Tuesdays and Wednesdays) exist between two dates in Java?
For example, from date 01/12 to 30/12, how many segundas, terças e quartas exist among them?

Using a lib with for example joda-time, you can do as in this post here, https://stackoverflow.com/questions/3802893/number-of-days-between-two-dates-in-joda-time

You want to count the days between two dates, but ignoring certain days of the week in the count, would be this?

He wants to count how many "Mondays, Tuesdays and Wednesdays" there are from a date D to a date D+N.

@LR10, the link you passed talks only about counting days between two dates, without taking into account the detail I mentioned, (I edited my reply)...

@Felipe.rce See if my edition agrees with what you’re wanting.

See this example in Ideone @Felipe.rce. Using only Java.

@Gustavocinque is exactly what I wanted!

Localdate startDate = new Localdate(2017, 11, 01); Localdate endDate = new Localdate(2017, 11, 30) Days days = Days.daysBetween(startDate, endDate). getDays() ;

You can do a for in days and take getDayOfWeek() for example and count the days. It’s a suggestion. As here https://stackoverflow.com/questions/15338196/joda-time-get-week-days

That’s right @LR10, came to see the example I put?

I’m waiting to reopen (I don’t know why they closed, since it was edited before it was closed) so I can accept the answer
