July 7

July 7 is the 188th day of the year (189th in leap years) in the Gregorian calendar. There are 177 days remaining until the end of the year. This date is slightly more likely to fall on a Tuesday, Thursday or Saturday (58 in 400 years each) than on Sunday or Monday (57), and slightly less likely to occur on a Wednesday or Friday (56).

The terms 7th July, July 7th, and 7/7 (pronounced "Seven-seven") have been widely used in the Western media as a shorthand for the 7 July 2005 bombings on London's transport system. In the Chinese language, this term is used to denote the Battle of Lugou Bridge started on July 7, 1937, marking the beginning of the Second Sino-Japanese War.
