A night club closing time is bound by prevailing laws.
In a bar, a last call (last orders) is an announcement made shortly before the bar closes for the night, informing patrons of their last chance to buy alcoholic beverages. There are various means to make this signal, like ringing a bell, flashing the lights, or announcing orally.
Last call times are often legally mandated and vary widely globally as well as locally. Legislation's purpose include reducing late night noise in the neighborhood, traffic accidents, violence, and alcohol related health problems.
List of last call times around the world
In New South Wales, there is no specified closing time, although in residential areas bars are often required to close at midnight. In non-residential areas some bars are open 24 hours.

Many bars, KTVs and night clubs have no specific last call and will continue to sell alcohol and stay open provided there are paying customers present. However, during sensitive times where national security is increased (i.e. the Olympics, the 60th Anniversary of the PRC) closing times may be in effect in some cities between 1 and 3 a.m. Alcohol is sold through retailers 24 hours a day.
According to the state law, establishments that serve drinks can register as bars, in which case they are allowed to be open in inhabited areas only in indoor spaces and only between 21:00 and 06:00, while no such restrictions exist if bars are located outside inhabited areas. Various exceptions can be made for bars located in transit facilities, if approved by the local authorities, etc. The prescribed working hours for bars are a frequent point of contention between city authorities and local businessmen, particularly during the summer tourist season.
The Dominican Republic has an alcohol curfew starting at 2:00AM, excepting on non-religious National Holidays. Not applicable on residential dwellings.
Bars are allowed to serve drinks until 1.30 a.m., but a provincial government may at the proprietor's request grant extensions up to 3.30 a.m. Extensions require the establishment to maintain a higher standard of amenities, service and entertainment by, for example, providing a coat check, entertainment programming such as a DJ or live music, and even general cleanliness and "look and feel" count.
A last call is not announced per se, but as a custom the lights are flashed a few times (or in case of a dimly lit establishment such as a night club, all lights are left on) to notify the customers that serving drinks is over.
Bar closing hours in Germany are regulated by the federated states or cities. Since the 2000s many federated states and cities have abolished or relaxed regulations. In many states and cities bars must close for a "cleaning hour" from 5 to 6 a.m. Open-air locations like beer gardens often must close at 11 p.m. or 12 a.m. to reduce noise pollution. Exceptions may exist for weekends, Carnival and New Year's Eve etc. Not all cities strictly enforce the regulation.
In Greece all bars, cafeterias, clubs and the like will stay open as long as there are customers inside. Usually cafeterias stay open until 11 p.m., bars until 2 a.m. and clubs until early in the morning, but there is no last call whatsoever. In 1994 Stelios Papathemelis who was the Minister for Public Order at the time passed a law mandating closing of all bars at 2 a.m. The law was widely unpopular, never materialized fully and was abolished few years later.

In Tel Aviv, bars are fined for remaining open past 1 AM. Though few bars actually close at that time, they are forced to pay this "back-door" tax to the municipality, with no recourse to the national government. A number of bars are contemplating closing at the required time and during internationally promoted events such as Gay Pride Week in protest of the city's underhanded hypocrisy in promoting itself as "the city that never sleeps" while at the same time fining the very establishments that make it such a hot tourist mecca.

- City-specific laws
Out of the 429 counties of Norway, almost 50% have established a closing time or "last call" at 2 a.m. Only 1 in 7 counties serve drinks until the laws maximum allowance at 3 a.m. This is a major decrease over the last few years, because of the governments beliefs in that reduced drinking hours equals less fighting, noise, disturbance, etc.
In Sweden explicit last calls do not take place, as it would violate a political principle not to encourage people to drink more. The latest allowed closing time of bars and restaurant is decided by the municipality, but regulated by national laws and rules. The standard latest time is 1 a.m. But in many cities a later time can be allowed on some conditions, like high security and staff educated in responsible serving of alcohol. In some of the largest cities, a closing time as late as 5 a.m. occurs.
