11. What time does Dunkin open?
Most Dunkin locations begin service very early; crew shift data suggests stores commonly open around 5:00 a.m. for customer service. Because Dunkin stores are franchise-operated, exact opening times vary by location (drive-thru only, 24-hour, etc.). It’s always best to check the specific store’s hours via the Dunkin’ app or store locator for the most accurate information.
12. Do Dunkin Refreshers have caffeine?
Yes, the Fruity “Refresher” line at Dunkin uses brewed green tea or green-tea extract as a base, so they contain caffeine. While a small only contains 66 mg of caffeine, the medium size contains 99 mg and the large contains 132 mg.
- A small size ≈ 66 mg caffeine.
- A medium size ≈ 99 mg.
- A large size ≈ 132 mg.
13. Is Dunkin open on Christmas?
Holiday hours vary a lot by franchise location. A 2024 report noted that while many Dunkin stores were open on Christmas Day, some were closed or operating with reduced hours, and recommended checking the mobile app. Bottom line: If you plan to visit on Christmas Day, check your local location’s hours in advance (via Dunkin’s app or store locator) because it may be closed or have reduced service.
14. Is Dunkin open on Thanksgiving?
Yes, many Dunkin locations do open on Thanksgiving Day, though exact hours may differ. For example: One 2024 article said “most Dunkin’ Donuts locations will be open on Thanksgiving Day, November 28, 2024.” As with other holidays, because hours vary by location/franchisee, it’s wise to check your local store for exact opening and closing times.
