Whenever empanelling of a jury or the taking of evidence on the trial of any case, shall have been begun, but not concluded, at the time at which there shall intervene any legal holiday or legal half-holiday, it is lawful for the presiding judge, and within his discretion, to order the trial to be proceeded with upon the legal holiday, if not a Sunday or Christmas day, or upon the legal half-holiday. All proceedings thereafter had in the trial of the case shall have the same force and effect as though had on a day not a legal holiday or legal half-holiday.
