Our kids get two weeks for Christmas. Always ending on a Friday and starting again on a Monday. The division between before/after Christmas depends on when Christmas falls as it always starts the Friday before Christmas. This year, the last day is the 19th and they go back on the 5th of January.
ETA - I'm pretty sure that if Christmas Day is a Saturday or Sunday, they get off the week before. So, in 2016, when Christmas Day is a Saturday, their last day of school will be the 16th and they'll go back on the 2nd.
Also, here (Ontario), Christmas Day, Boxing Day (26-December) and New Year's day are all Statutory Holidays.[/QUOTE
In 2016 Christmas is actually on Sunday. That pesky leap year makes us miss out on Christmas Saturday.
As for school breaks, our kid's last day is the 19th. Then they have to go back 5th of January.
