Vrian7 :
Working with Java, I'm parsing a integer DAYS to HOURS.
Looks like this:
float hours = myvardays*24;
It works, but constant 24 is a magic number, and best avoided.
Is there any constant on Calendar, Date or any other to get total hours in a day (24)? or maybe a method?
I am interested only in generic 24-hours, ignoring anomalies such as Daylight Saving Time (DST) that result in other day lengths.

Let's not go reinventing stuff, this is all baked into the JDK:
Java 8 and later
Use Duration.ofDays with toDays method.
long hours = Duration.ofDays(myvardays).toHours(); // Java 8+
Java 5, 6, & 7
Use the TimeUnit enum.
long hours = TimeUnit.DAYS.toHours(myvardays); // Java 5+
