The best answer depends on your location, since fireworks laws and sale windows vary by country, state, and even local jurisdictions. Here’s a practical overview to help you plan. What to consider

• Location matters: Some places allow sales only during specific windows and may require licenses or permits for retailers. Retailers in many regions operate under seasonal licenses, restricting when you can buy.
• Age restrictions: Many regions restrict sales to adults; some states or countries impose higher age limits for fireworks purchases.
• Type of fireworks: Consumer-grade fireworks (for home use) are often restricted differently from professional/display fireworks. Sparklers and novelty items may have separate rules in some places.
• Discharge rules: In addition to when you can buy, there are often rules about when you can light or discharge fireworks, sometimes with additional restrictions during droughts or fire bans.
• Local updates: Fireworks regulations can change year to year, especially around holidays like Independence Day or New Year, or during periods of drought or fire danger.

What you can do now

• Check your local government or fire department website for the most current “fireworks calendar” or consumer fireworks regulations for your city, county, or state.
• Contact licensed retailers in your area; they typically publish the permitted sale windows and any required permits.
• If you’re traveling, research the destination’s rules in advance, as even neighboring regions can have different laws.

If you’d like, share your country, state/province, and city, and I can tailor the guidance to your exact location and provide the typical sale windows and any known restrictions for that area.
