Those drums of dawn are for waking up people to have their last meal before fasting. Like a human alarm

It is a common habit in Muslim countries and areas. But the drum sound should me mild and not annoying.

In some places where the community or neighborhood is small, the drummer used to call every person by name to wake him and his family up. Can call it a "nice to have".

Thank you for bringing this up. Completely forgot about it. Unfortunately or or fortunately (to your husband) this habt is vanishing

Never knew about fireworks. Usually, they use cannons with sound shells to announce start and end of fasting. i.e. at dawn and sunset.
