> String(new Date("2018/01/01")); < "Mon Jan 01 2018 00:00:00 GMT-0800 (Pacific Standard Time)" > String(new Date("2018-01-01")); < "Sun Dec 31 2017 16:00:00 GMT-0800 (Pacific Standard Time)" >

A JavaScript console shows two nearly identical date strings producing different results: the slash-separated date is interpreted as January 1, while the hyphen-separated date becomes December 31 at 4 PM in the previous time zone. The joke mocks JavaScript's confusing and inconsistent date parsing, making it useful as a reaction to bizarre programmer behavior.
