Joda-time: First day in this year's ISO week 1

Question

I would like to find out the date of the Monday in this year's ISO week 1 (For 2009 this would be Monday, Dec 29 2008).

I'm sure that joda-time can handle this, but I just can't figure out the API (maybe it's just too late).

Can anyone help? Thanks!

Answer 1

I believe this should work:

DateMidnight date = new DateMidnight().withWeekOfWeekyear(1).withDayOfWeek(1);

Answer 2

The DateMidnight API mentioned in the other answer is now deprecated, use below:

DateTime date = new DateTime().dayOfYear().withMinimumValue().withTimeAtStartOfDay();
