Black Friday began earlier than ever this year, with Walmart kicking off holiday discounts on TVs, air fryers and trampolines in October.

Now, after weeks of "Early Black Friday" sales and "HoliDeals," it's finally time for the busiest shopping weekend of the year. Roughly 165 million Americans are expected to shop during the five days between Thanksgiving and Cyber Monday, according to the National Retail Federation.

And though a growing number of Americans say they'll be buying online this holiday season, retailers are continuing their tradition of in-store doorbusters and ever-earlier openings. For those planning to shop the old-fashioned way, here's a roundup of what's opening when.

Thanksgiving Day

6am: Kmart is among the first to open its stores, with doorbuster deals that include $19 Nerf water guns and $25 weighted blankets. Stores will stay open until midnight.
