When is the best time to set off fireworks and firecrackers?
New Year's Eve & Spring Festival: Two tiers. 19:00-21:00 around dinner suits family sparklers; countdown 23:00-00:10 needs local check post-22:00.
Grand openings/weddings: Prefer 18:30-20:00 for atmosphere. Daytime only for cold sparks, not large shells.
Birthdays/indoor cold fireworks: After dusk lights on, no strict limit, avoid late night.
Considering visuals, rest, noise, and fire safety, 19:00—21:30 after dark is optimal. Best visuals: colors pop in darkness. Neighbor-friendly: less sleep disruption. Safe operation: ambient light helps spot fuses/debris. Also suits New Year's Eve/Spring Festival: 19:00-21:00 for family sparklers; countdown 23:00-00:10 needs local check post-22:00.
