Simple DateTime class in Java

So I've been going over some of the date classes in java and in popular libraries, and they all seem overly bloated, or are too bugged/complicated for me to use. The closest I've found is Java's Calendar class. But it's still too complicated. So I'm looking for a super simple DateTime class.

I need this for an Android app I'm currently working on. In this app I read a week schedule from a website to display in my app. So all I need is:

• years
• months
• perhaps also weeks, but I can read that from the schedule as well
• days
• hours
• minutes

Second and millisecond precision are not necessary. I also don't need timezones, since the app is only for my current college. The only support I need for special cases is:

• days per month (28, 30, 31)
• leap years

I know already that someone will probably suggest Joda-Time, but it's bloated, and I've read multiple reports about how slow it is on Android.

As suggested by Sebastiaan van den Broek, I decided to make my own simple class for storing dates and times. If anyone should need it, I included the code.

Be aware that there's only support for storing dates and times generated by a system that accounts for leap years, time zones, etc. There are probably also a couple of functions missing for simple storage, but this class is - at the moment - sufficient for my case.

/**
 * A simple class for storing dates and times.
 * There is no support for time zones, leap years, etc.
 * So only use this when you're certain the dates and times you're storing are generated with special cases in mind.
