Julian Google

The “Gregorian Calendar(Gregorian Calendar)”:http://scienceworld.wolfram.com/astronomy/GregorianCalendar.html has been in use since 1582 during the Papacy of “Gregory XIII(Gregory XIII)”:http://www.newadvent.org/cathen/07001b.htm. But Google, which has been in “existence quite a few less years(Sergey Brin’s Home Page)”:http://www-db.stanford.edu/~sergey/, still uses “Julian dates(Google by date)”:http://www.lifehacker.com/software/search-engines/google-by-date-101891.php. How about joining the rest of us in the 17th century?
