So the groundhog saw his shadow today, implying six more weeks of Winter. Let’s settle this nonsense once and for all.
[sourcecode language=”java”]
def cal = Calendar.instance
cal.set(2009,Calendar.FEBRUARY,2)
def ghday = cal.time
cal.set(2009,Calendar.MARCH,21)
def spring = cal.time
def days = (ghday..spring).size()
println “Between Feb 2 and Mar 21, there are $days days”
[/sourcecode]
The output is
[sourcecode language=”java”]
Between Feb 2 and Mar 21, there are 48 days
[/sourcecode]
In other words, there are six weeks and six days between Groundhog Day and the first day of Spring. So we’re already going to have an early Spring. 🙂
nice tips.
btw, you should try joda-time. it is very nice to play with date.
Yes, I’m familiar with joda time, but for something this simple it was easy enough to use the regular Calendar class.
lol! And I learned something about date ranges, too. Thanks!
i am interested with this date range
[code] def days = (ghday..spring).size() [/code]
can you tell me what kind of object that has “range” features .. I tought it was only applied to Integer but now you showed us that it can be applied to java.util.Date object. that’s amazing.
I live in the southern hemisphere, so it’s summer here, but I liked how you played with calendars anyway…
