World Calendar
The World Calendar is a proposed reform of the Gregorian calendar created by Elisabeth Achelis of Brooklyn, New York in 1930. Features The World Calendar is a 12-month, perennial calendar with equal quarters. Each quarter begins on a Sunday and ends on a Saturday. The quarters are equal: each has exactly 91 days, 13 weeks, or 3 months. The three months in each quarter have 31, 30, and 30 days respectively. Each quarter begins with the 31-day months of January, April, July, or October. The World Calendar also has the following two additional days to maintain the same new year days as the Gregorian calendar. ; Worldsday : The last day of the year following Saturday 30 December. This additional day is dated "W" and named Worldsday, a year-end world holiday. It is followed by Sunday, 1 January in the new year. ; Leapyear Day : This day is similarly added at the end of the second quarter in leap years. It is also dated "W" and named Leapyear Day. It is followed by Sunday, 1 July ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Calendar Reform
Calendar reform or calendrical reform is any significant revision of a calendar system. The term sometimes is used instead for a proposal to switch to a different calendar design. Principles The prime objective of a calendar is to unambiguously identify any day in past, present and future by a specific date in order to record or organize social, religious, commercial or administrative events. Recurring periods that contain multiple days, like weeks, months and even years, are secondary, convenient features of a calendar. Most cultures adopt a primary dating system, but different cultures have always needed to align multiple calendars with each other, because they coexisted in the same space (e.g. secular and religious groups with different demands) or had established trading relations. Once specified, a ''calendar design'' cannot be altered without becoming a new design. If a proposed design is sufficiently close to the legacy one, i.e. compatible with it, a ''reform'' of th ...

Armelin's Calendar
Armelin's calendar was developed around 1887 by French astronomer , who developed a twelve-month calendar in which the year of 364 days was divided into four equal quarters of 91 days. Armelin's calendar proposal was discussed chiefly under the auspices of the Société astronomique de France in 1887 and recently in the French Academy of Sciences. Structure # The year is divided into four quarters of three months each, and the arrangements for the first quarter repeat in each of the other quarters. The first and second month of each quarter have thirty days, and the third month 31 days. This accounts for 91 days in each quarter, or 364 days in all. # The remaining day in ordinary years is "New Year's Day". It is given no other descriptive title. It does not belong to any week or any month. It begins the year. January 1 is the day following New Year's Day. # The 366th day of leap year is likewise an extra day, bearing an appropriate descriptive name, perhaps ...

List Of Calendars
This is a list of calendars. Included are historical calendars as well as proposed ones. Historical calendars are often grouped into larger categories by cultural sphere or historical period; thus O'Neil (1976) distinguishes the groupings Egyptian calendars (Ancient Egypt), Babylonian calendars (Ancient Mesopotamia), Indian calendars (Hindu and Buddhist traditions of the Indian subcontinent), Chinese calendars and Mesoamerican calendars. These are not specific calendars but series of historical calendars undergoing reforms or regional diversification. In Classical Antiquity, the Hellenic calendars inspired the Roman calendar, including the solar Julian calendar introduced in 45 BC. Many modern calendar proposals, including the Gregorian calendar introduced in 1582 AD, contains modifications from that of the Julian calendar. List of calendars In the list below, specific calendars are given, listed by calendar type (solar, lunisolar or lunar), time of introduction (if known ...

ISO 8601
ISO 8601 is an international standard covering the worldwide exchange and communication of date and time-related data. It is maintained by the Geneva-based International Organization for Standardization (ISO) and was first published in 1988, with updates in 1991, 2000, 2004, and 2019, and an amendment in 2022. The standard provides a well-defined, unambiguous method of representing calendar dates and times in worldwide communications, especially to avoid misinterpreting numeric dates and times when such data is transferred between countries with different conventions for writing numeric dates and times. ISO 8601 applies to these representations and formats: ''dates,'' in the Gregorian calendar (including the proleptic Gregorian calendar); ''times,'' based on the 24-hour timekeeping system, with optional UTC offset; ''time intervals''; and combinations thereof.ISO 8601:2004 section 1 Scope The standard does not assign specific meaning to any element of the dates/times ...

Seventh-day Adventist Church
The Seventh-day Adventist Church is an Adventist Protestant Christian denomination which is distinguished by its observance of Saturday, the seventh day of the week in the Christian (Gregorian) and the Hebrew calendar, as the Sabbath, and its emphasis on the imminent Second Coming (advent) of Jesus Christ. The denomination grew out of the Millerite movement in the United States during the mid-19th century and it was formally established in 1863. Among its co-founders was Ellen G. White, whose extensive writings are still held in high regard by the church. Much of the theology of the Seventh-day Adventist Church corresponds to common evangelical Christian teachings, such as the Trinity and the infallibility of Scripture. Distinctive post-tribulation teachings include the unconscious state of the dead and the doctrine of an investigative judgment. The church places an emphasis on diet and health, including adhering to Kosher food laws, advocating vegetarianism, and its ...

Jumu'ah
In Islam, Friday prayer or Congregational prayer ( ar, صَلَاة ٱلْجُمُعَة, ') is a prayer ('' ṣalāt'') that Muslims hold every Friday, after noon instead of the Zuhr prayer. Muslims ordinarily pray five times each day according to the sun's sky path regardless of time zones. ''Jumu’ah'' means Friday in the Arabic language. In many Muslim countries, the weekend is inclusive of Fridays, while in others, Fridays are half-days for schools and some workplaces. Meaning It is one of the most exalted Islamic rituals and one of its confirmed obligatory acts. Obligation There is consensus among Muslims regarding the Friday prayer (''salat al-jum‘ah'') being ''wajib'' - required - in accordance with the Quranic verse, as well as the many traditions narrated both by Shi’i and Sunni sources. According to the majority of Sunni schools and some Shiite jurists, Friday prayer is a religious obligation, but their differences were based on whether its obligation is co ...

Lord's Day
The Lord's Day in Christianity is generally Sunday, the principal day of communal worship. It is observed by most Christians as the weekly memorial of the resurrection of Jesus Christ, who is said in the canonical Gospels to have been witnessed alive from the dead early on the first day of the week. The phrase appears in . According to some sources, Christians held corporate worship on Sunday in the 1st century. ('' First Apology''chapter 67, and by 361 AD it had become a mandated weekly occurrence. Before the Early Middle Ages, the Lord's Day became associated with Sabbatarian (rest) practices legislated by Church Councils. Christian denominations such as the Reformed Churches, Methodist Churches, and Baptist Churches regard Sunday as Christian Sabbath, a practice known as first-day Sabbatarianism. First-day Sabbatarian (Sunday Sabbatarian) practices include attending morning and evening church services on Sundays, receiving catechesis in Sunday School on the Lord's Day, ...

Sabbath In Christianity
Sabbath in Christianity is the inclusion in Christianity of a Sabbath, a day set aside for rest and worship, a practice that was mandated for the Israelites in the Ten Commandments in line with God's blessing of the seventh day (Saturday) making it holy, "because on it God rested from all his work that he had done in creation". The practice was associated with the assembly of the people to worship in synagogues on the day known as Shabbat. Early Christians, at first mainly Jewish, observed the seventh-day Sabbath with prayer and rest, but gathered on the seventh day, Saturday, reckoned in Jewish tradition as beginning, like the other days, at sunset on what would now be considered the Friday evening. At the beginning of the second century Ignatius of Antioch approved non-observance of the Sabbath. The now majority practice of Christians is to observe Sunday, called the Lord's Day, rather than the Jewish seventh-day Sabbath as a day of rest and worship. Possibly because of a moveme ...

Remember The Sabbath Day, To Keep It Holy
"Remember the sabbath day, to keep it holy" (Hebrew: ''zāḵōr ’eṯ-yōm haš- šabbāṯ lə- qaddəšōw'') is one of the Ten Commandments found in the Torah. The full text of the commandment reads: Background According to the biblical narrative when God revealed the Ten Commandments to the Israelites at biblical Mount Sinai, they were commanded to remember the Sabbath and keep it holy by not doing any work and allowing the whole household to cease from work. This was in recognition of God's act of creation and the special status that God had conferred on the seventh day during the creation week. Ancient understanding The Torah portrays the Sabbath concept both in terms of resting on the seventh day and allowing land to lie fallow during each seventh year. The motivation is described as going beyond a sign and remembrance of Yahweh's original rest during the creation week and extends to a concern that one's servants, family, and livestock be able to rest and be refres ...

Ten Commandments
The Ten Commandments (Biblical Hebrew עשרת הדברים \ עֲשֶׂרֶת הַדְּבָרִים, ''aséret ha-dvarím'', lit. The Decalogue, The Ten Words, cf. Mishnaic Hebrew עשרת הדיברות \ עֲשֶׂרֶת הַדִּבְּרוֹת, ''aséret ha-dibrót'', lit. The Decalogue, The Ten Words), are a set of biblical principles relating to ethics and worship that play a fundamental role in Judaism and Christianity. The text of the Ten Commandments appears twice in the Hebrew Bible: at Exodus and Deuteronomy . According to the Book of Exodus in the Torah, the Ten Commandments were revealed to Moses at Mount Sinai and inscribed by the finger of God on two tablets of stone kept in the Ark of the Covenant. Scholars disagree about when the Ten Commandments were written and by whom, with some modern scholars suggesting that they were likely modeled on Hittite and Mesopotamian laws and treaties.

Shabbat
Shabbat (, , or ; he, שַׁבָּת, Šabbāṯ, , ) or the Sabbath (), also called Shabbos (, ) by Ashkenazim, is Judaism's day of rest on the seventh day of the week—i.e., Saturday. On this day, religious Jews remember the biblical stories describing the creation of the heaven and earth in six days and the redemption from slavery and The Exodus from Egypt, and look forward to a future Messianic Age. Since the Jewish religious calendar counts days from sunset to sunset, Shabbat begins in the evening of what on the civil calendar is Friday. Shabbat observance entails refraining from work activities, often with great rigor, and engaging in restful activities to honour the day. Judaism's traditional position is that the unbroken seventh-day Shabbat originated among the Jewish people, as their first and most sacred institution. Variations upon Shabbat are widespread in Judaism and, with adaptations, throughout the Abrahamic and many other religions. According to ''halak ...
