Christmas and Hanukkah are both less than two weeks away. Between shopping for presents, tackling last-minute work deadlines, and preparing for out-of-town guests, you’ll likely need extra caffeine to check all the items off your holiday to-do list. Luckily, Dunkin’ Donuts has your back. As Travel + Leisure reports, select DD locations across the U.S. will be giving away free medium hot coffees on certain days throughout December.

The promotion began today, and runs until Friday, December 23. The first 500 guests to stop at the participating locations each day will receive a complimentary beverage. In the spirit of seasonal generosity, the chain also plans to donate $1000 to local children’s charities in each city serving free coffee.

Not all store locations have been finalized just yet, but here’s an itinerary of cities where customers can get their caffeine fix for free. For a full, updated list of restaurants, check back with the Dunkin’ Donuts blog. (Sorry, Chicago residents, you likely missed your chance, as your local DD giveaway took place today.)
