Chahârshanbe-suri (the festive Wednesday before Nowruz) sees stronger public celebration in Tehran, Tabriz, and other large cities, where firework explosions and bonfires fill streets and parks; the noise level is often a public order concern. Smaller cities (Yazd, Kerman) tend toward quieter household-level fires. Iranian Zoroastrians, who trace the ritual to pre-Islamic fire reverence, have their own observances in Yazd and the Kerman region. Diaspora communities adapt with backyard fires or candles where local laws prohibit fireworks.
