You should know:
Holidays falling on a weekend are not moved.
Metal workers have the holiday of St. Eloi on 1 December
Note that when a holiday happens to fall on a Tuesday or
Thursday, many French workers may take the Monday or, respectively,
Friday, off as well. This is not official and does not apply to
institutions such as banks or government, but is sufficiently
commonplace to cause difficulties doing business on occasion.
