Thursday in the context of "Common year starting on Thursday"

A leap year starting on Thursday is any year with 366 days (i.e. it includes 29 February) that begins on Thursday 1 January, and ends on Friday 31 December. Its dominical letters hence are DC. The most recent year of such kind was 2004, and the next one will be 2032 in the Gregorian calendar or, likewise, 2016 and 2044 in the obsolete Julian calendar.

This is the only leap year with three occurrences of Tuesday the 13th: those three in this leap year occur three months (13 weeks) apart: in January, April, and July. Common years starting on Monday share this characteristic, in the months of February, March, and November.

Friday is the day of the week between Thursday and Saturday. In countries adopting the "Monday-first" convention it is the fifth day of the week. In countries that adopt the "Sunday-first" convention, it is the sixth day of the week.

In most Western countries, Friday is the fifth and final day of the working week. In some other countries, Friday is the first day of the weekend, with Saturday the second.In Israel, Friday is the sixth day of the week. In Iran, Friday is the last day of the weekend, with Saturday as the first day of the working week. Bahrain, the United Arab Emirates (UAE), Saudi Arabia and Kuwait also followed this convention until they changed to a Friday–Saturday weekend on September 1, 2006, in Bahrain and the UAE, and a year later in Kuwait. UAE recently changed its weekend from Friday-Saturday to Saturday-Sunday.

A leap year starting on Wednesday is any year with 366 days (i.e. it includes 29 February) that begins on Wednesday 1 January and ends on Thursday 31 December. Its dominical letters hence are ED. The most recent year of such kind was 2020, and the next one will be 2048 in the Gregorian calendar, or likewise, 2004 and 2032 in the obsolete Julian calendar, see below for more.

Any leap year that starts on Wednesday has two Friday the 13ths: those two in this leap year occur in March and November. Common years starting on Thursday share this characteristic, but also have another in February.

The vatër (or votër; Albanian definite form: vatra or votra) is the domestic hearth in Albanian culture. The fire of the domestic hearth (Zjarri i Vatrës) holds divine attributes in Albanian beliefs, being considered the sustainer of the continuity between the world of the living and that of the dead, and ensuring the continuity of the tribe (fis) from generation to generation. The absence of fire in a house is traditionally considered a great curse. In Albanian folk beliefs the fire hearth is the symbol of fire as the offspring of the Sun (Dielli). In Albanian tradition the deified fire (zjarri) was evidently also called with the theonym Enji, the god to whom Thursday – e enjte – was dedicated in the Albanian language.

Enji (Albanian: [ɛɲi]) is the old name of the fire god in the Albanian pagan mythology evidently contained in the weekday name that was dedicated to him – e enjte – the Albanian word for Thursday. The Fire – Zjarri – is deified in Albanian tradition as releaser of light and heat with the power to ward off darkness and evil, affect cosmic phenomena and give strength to the Sun (Dielli, who is worshiped as the god of light, sky and weather, giver of life, health and energy, and all-seeing eye), and as sustainer of the continuity between life and afterlife and between the generations. The divine power of Fire is used for the hearth and the rituals, including calendar fires, sacrificial offerings, divination, purification, and protection from big storms and other potentially harmful events. Fire worship and rituals are associated with the cult of the Sun (Dielli), the cult of the hearth (vatër) and the ancestor, and the cult of fertility in agriculture and animal husbandry. Fire rituals that are commonly found among Indo-European peoples, including the Albanians, have been firstly attested by the Vedas, with hymns dedicated to the fire god Agni. Described in written sources since 1482, the Albanian fire rituals have been historically fought by the Christian clergy, without success. The cult of the mystic fire and the fire ritual practices have played a prominent role in the lives of all the Albanian people until the 20th century, and in rural areas they continue to be important for Albanian traditional customs even in the present days.

The theonym from which Thursday was named in Albanian is considered to have been attested in antiquity in Illyrian theophoric names with the Latin spelling En(n)-. He was presumably worshiped by the Illyrians in antiquity and he may have been the most prominent god of the Albanian pantheon in Roman times by interpreting Jupiter, when weekday names were formed in the Albanian language. The belief in a prominent fire and wind god, who was referred to as I Verbti ("the blind one"), and who was often regarded more powerful than the Christian God, survived in northern Albania until recent times. Under Christianization the god of fire was demonized and considered a false god, and it was spread about that anyone who invoked him would be blinded by fire. The purifying power of fire underlies the Albanian folk belief according to which the fire god is the enemy of uncleanliness and the opponent of filth.
