The California Senate has passed a bill to allow last call to be extended to 4 a.m. at bars throughout the state. Currently, the state law establishes last call no later than 2 a.m., with many establishments in big cities shutting down their own nightlife scenes even earlier.

Under the new Senate bill, municipalities would now have the option to extend the law to as late as 4 a.m. — though they’re not obligated to do so.

Though the bill has passed in the state Senate, it still has other hurdles to jump in order to become law. It will move onto the state Assembly next, then the Governor’s office. State Senator Scott Wiener, who introduced the initial idea for the bill, wrote in a statement about the financial benefits of pushing last call:

"Nightlife matters a lot, culturally and economically, and it's time to allow local communities more flexibility."

Back in 2010, a City of San Francisco study estimated that nightlife establishments generated over $4.2 million in spending that year. Considering the area’s growth since then, it’s likely that number’s increased since then. Other large California municipalities like Los Angeles, San Diego, and Long Beach (among others) generate similar or larger spending an annual basis. Adding another two hours to the nightlife in cities like those could bring even more money to local businesses.
