Tuesday in the context of "Týr"

Týr (/tɪər/; Old Norse: Týr, pronounced [tyːr]) is a god in Germanic mythology and member of the Æsir. In Norse mythology, which provides most of the surviving narratives about gods among the Germanic peoples, Týr sacrifices his right hand to the monstrous wolf Fenrir, who bites it off when he realizes the gods have bound him. Týr is foretold of being consumed by the similarly monstrous dog Garmr during the events of Ragnarök.

The interpretatio romana generally renders the god as Mars, the ancient Roman war god, and it is through that lens that most Latin references to the god occur. For example, the god may be referenced as Mars Thingsus (Latin 'Mars of the Assembly [Thing]') on 3rd century Latin inscription, reflecting a strong association with the Germanic thing, a legislative body among the ancient Germanic peoples. By way of the opposite process of interpretatio germanica, Tuesday is named after Týr ('Týr's day'), rather than Mars, in English and other Germanic languages.

A common year starting on Tuesday is any non-leap year (i.e. a year with 365 days) that begins on Tuesday, 1 January, and ends on Tuesday, 31 December. Its dominical letter hence is F. The most recent year of such kind was 2019, and the next one will be 2030, or, likewise, 2025 and 2031 in the obsolete Julian calendar, see below for more.

Any common year that starts on Tuesday has two Friday the 13ths: those two in this common year occur in September and December. Leap years starting on Monday share this characteristic. From July of the year preceding this year until September in this type of year is the longest period (14 months) that occurs without a Friday the 13th. Leap years starting on Saturday share this characteristic, from August of the common year that precedes it to October in that type of year.

A leap year starting on Tuesday is any year with 366 days (i.e. it includes 29 February) that begins on Tuesday, 1 January, and ends on Wednesday, 31 December. Its dominical letters hence are FE. The most recent year of such kind was 2008, and the next one will be 2036 in the Gregorian calendar or, likewise 2020 and 2048 in the obsolete Julian calendar.

Any leap year that starts on Tuesday has only one Friday the 13th; the only one in this leap year occurs in June. Common years starting on Wednesday share this characteristic.
