Bucharest has hundreds of bus and trolleybus routes, and tens of trams, serving every part of the city as well as a number of suburban villages and outposts.  Buses and trams run at infrequent intervals from very early in the morning (around 04:30) to around 22:50 (earlier at weekends), after which the night buses takeover. These serve all areas of the capital throughout the night, with all routes departing from Piata Unirii. Most night bus services run at hourly intervals.
