Core answer:
On Veterans Day, many government offices close, and post offices typically close, while banks may close or have reduced hours. Retailers and restaurants usually stay open, and stock markets typically operate. Details:

• Government offices and courts: Most are closed on Veterans Day as it is a federal holiday, though local governments may have different schedules. [example sources indicate closures for federal offices]
• Post offices: Generally closed, so mail delivery is suspended or limited. [typical USPS practice on federal holidays]
• Banks and financial markets: Banks often close; stock markets generally stay open for trading, though some financial services may have limited hours. [common patterns cited in 2020–2025 coverage]
• Retailers and restaurants: Largely open, with many offering Veterans Day discounts or promotions. Hours vary by location. [promotions and open status commonly reported]
• Other services: Public transit and utility services usually operate, but some municipal services may be affected depending on local decisions. [vary by location]

Notes:

• If you’re planning around a specific location, it’s best to check local government websites, your bank, and your post office for the exact holiday hours.
