Cleaning holidays?

Why do politicians and workers alike drop everything on the last Saturday of every month?

The reason: Umuganda – a nationwide community work program aimed at keeping Rwanda’s cities clean – takes place on the last Saturday of every month. Between the hours of 7:00 am and noon, all businesses and public transportation close down. Everyone in society -- including the president – participates in the cause.

The mandatory work program is also a chance for neighbors to meet and discuss local issues.
The government also uses the opportunity to make announcements or presentations.

However, not everyone is eager to participate. Skipping this monthly ritual does have its consequences. Failing to participate leads to automatic arrest.
