In the New Orleans area it is basically the last week of August, or maybe a little earlier for 1/2 a week. We get out at the very end of May, or sometimes June 1st or so, depending on the calendar.
We get a four day break in Oct. (conferences) only 2 days at Thanksgiving, two weeks at Christmas, one week for Mardi Gras (usually in February), a week for Easter, and another four days right before the end of the year for more conferences, with a few days mixed in between here and there.
