Getsuku

is a Japanese abbreviation for . This is traditionally the time when the most popular TV dramas air in Japan.

==History== Fuji TV, one of the major broadcasting companies in Japan, started the pattern of airing the dramas it predicted would be most popular on Monday nights. Mondays are the only night in which generally no baseball games are played, meaning that throughout the year, there would be no delays in broadcasting (due to the popularity of baseball, some stations continue to broadcast games that extend beyond their expected finish time, thus delaying the start of subsequent programs).
