Tu Bishvat (Hebrew: ט״ו בשבט‎) is a minor Jewish holiday, occurring on the 15th day of the Hebrew month of Shevat (in 2012 this occurred from sunset on February 7 through the time when you can see three stars in the sky on February 8). It is also called "Rosh HaShanah La'Ilanot" (Hebrew: ראש השנה לאילנות‎), which means the "New Year of the Trees". Tu Bishvat is one of four "New Years" mentioned in the Mishnah.

The name Tu Bishvat is derived from the Hebrew date of the holiday, which occurs on the fifteenth day of Shevat. "Tu" stands for the Hebrew letters Tet and Vav, which together have the numerical value of 9 and 6, adding up to 15. Tu Bishvat is a relatively recent name; the date was originally called "Ḥamisha Asar BiShvat" (חמשה-עשר בשבט), which means "Fifteenth of Shevat".^{[citation needed]}

Tu Bishvat appears in the Mishnah in Tractate Rosh Hashanah as one of the four new years in the Jewish calendar. The discussion of when the New Year occurs was a source of debate among the rabbis: "And there are four new year dates: - The first of Nisan - new year for kings and festivals - The first of Elul - new year for animal tithes. Rabbi Elazar and Rabbi Shimon say: the first of Tishrei. - The first of Tishrei- new year for calculation of the calendar, sabbatical years and jubilees, for planting and sowing - The first of Shevat, according to the school of Shamai; The school of Hillel say: the fifteenth of Shevat" (Rosh Hashana:2a)

The Nice were an English progressive rock band from the 1960s, known for their blend of rock, jazz and classical music. Their debut album, The Thoughts of Emerlist Davjack was released in 1967 to immediate acclaim. It is often considered the first progressive rock album. The Nice are also a forerunner of the much more widely known Emerson, Lake & Palmer.

The Nice consisted initially of keyboardist Keith Emerson, bassist/vocalist Lee Jackson, drummer Brian Davison, and guitarist David O'List, more commonly known as "Davy". The band took their name from Steve Marriott's slang term for being high, a term he used in the song "Here Come the Nice". Marriott originally wanted to give the name to a band he was producing, called The Little People. Andrew Loog Oldham took it upon himself to rename The Little People Apostolic Intervention, and dubbed the Emerson, Jackson, Davison, O'List group "The Nice". Emerson's autobiography Pictures of an Exhibitionist suggests that the name originated with a suggestion from P. P. Arnold. The reference to "being high" is not mentioned, instead a routine by hipster/comic Lord Buckley is quoted.
