Hiring during the holidays

Good morning everyone. I’ve been anxiously awaiting my mmd approval so I can get to work. Now that I have that credential I am planning on a/several trips to the bayou to knock on doors. I have heard that landing a job during the holiday season is sometimes easier because of holiday turnover. Since this industry is so different from what I am used to I was wondering if the HR offices keep normal people time or is hiring a 7 day a week business?
