Sorry, New Yorkers—you officially spend more time commuting to work than residents of any other U.S. city do, with an average of 6 hours and 18 minutes spent going back and forth per week.

That time spent also gives New York the designation of having the longest average work week in the country, according to a new economic brief from the city’s comptroller’s office. Now you know why the city never sleeps.

Technically, San Francisco residents work more hours than New Yorkers do on average, but because their commute times are shorter by roughly an hour and a half per week, their work weeks are ultimately shorter too.

Of the 30 major cities surveyed, Chicago had the second-longest weekly commute time (5 hours, 25 minutes) while the Louisville, Ky., area had the shortest, with residents only traveling for about three hours and 27 minutes.
