Father's DayFather's Day is a holiday honoring one's father, or relevant father figure, as well as fatherhood, paternal bonds, and the influence of fathers in society. The single most common date among world countries is the third Sunday of June, which was founded in the state of Washington, United States, by Sonora Smart Dodd in 1910. The day is held on various dates across the world, and different regions maintain their own traditions of honoring fatherhood. In some Catholic countries of Europe, it has been celebrated on 19 March as Saint Joseph's Day since the Middle Ages.
Daylight saving timeDaylight saving time (DST), also referred to as daylight savings time, daylight time (United States, Canada, and Australia), or summer time (United Kingdom, European Union, and others), is the practice of advancing clocks (typically by one hour) during warmer months so that darkness falls at a later clock time. The typical implementation of DST is to set clocks forward by one hour in either the late winter or spring ("spring forward"), and to set clocks back by one hour in the fall ("fall back") to return to standard time.
Children's DayChildren's Day is a commemorative date celebrated annually in honor of children, whose date of observance varies by country. In 1925, International Children's Day was first proclaimed in Geneva during the World Conference on Child Welfare. Since 1950, it is celebrated on June 1 in many countries. World Children's Day is celebrated on 20 November to commemorate the Declaration of the Rights of the Child by the UN General Assembly on 20 November 1959. In some countries, it is Children's Week and not Children's Day.
Public holidayA public holiday, national holiday, federal holiday, statutory holiday, or legal holiday is a holiday generally established by law and is usually a non-working day during the year. A civic holiday, also known as a civil or work holiday, is a day that is legally recognized and celebrated as a holiday in a particular sovereign state or jurisdictional subdivision of such, e.g., a state or a province. It is usually a day that the legislature, parliament, congress or sovereign has declared by statute, edict or decree as a non-working day when the official arms of government such as the court system are closed.
Common EraCommon Era (CE) and Before the Common Era (BCE) are year notations for the Gregorian calendar (and its predecessor, the Julian calendar), the world's most widely used calendar era. Common Era and Before the Common Era are alternatives to the original Anno Domini (AD) and Before Christ (BC) notations used for the same calendar era. The two notation systems are numerically equivalent: " CE" and "AD " each describe the current year; "400 BCE" and "400 BC" are the same year.
Javanese calendarThe Javanese calendar (Pananggalan Jawa) is the calendar of the Javanese people. It is used concurrently with two other calendars, the Gregorian calendar and the Islamic calendar. The Gregorian calendar is the official calendar of the Republic of Indonesia and civil society, while the Islamic calendar is used by Muslims and the Indonesian government for religious worship and deciding relevant Islamic holidays.
Before PresentBefore Present (BP) years, also known as "time before present" or "years before present (YBP)", is a time scale used mainly in archaeology, geology and other scientific disciplines to specify when events occurred relative to the origin of practical radiocarbon dating in the 1950s. Because the "present" time changes, standard practice is to use 1 January 1950 as the commencement date (epoch) of the age scale.
Solar calendarA solar calendar is a calendar whose dates indicate the season or almost equivalently the apparent position of the Sun relative to the stars. The Gregorian calendar, widely accepted as a standard in the world, is an example of a solar calendar. The main other types of calendar are lunar calendar and lunisolar calendar, whose months correspond to cycles of Moon phases. The months of the Gregorian calendar do not correspond to cycles of the Moon phase.
EpochIn chronology and periodization, an epoch or reference epoch is an instant in time chosen as the origin of a particular calendar era. The "epoch" serves as a reference point from which time is measured. The moment of epoch is usually decided by congruity, or by following conventions understood from the epoch in question. The epoch moment or date is usually defined from a specific, clear event of change, an epoch event. In a more gradual change, a deciding moment is chosen when the epoch criterion was reached.
Calendar eraA calendar era is the period of time elapsed since one epoch of a calendar and, if it exists, before the next one. For example, it is the year as per the Gregorian calendar, which numbers its years in the Western Christian era (the Coptic Orthodox and Ethiopian Orthodox churches have their own Christian eras). In antiquity, regnal years were counted from the accession of a monarch. This makes the chronology of the ancient Near East very difficult to reconstruct, based on disparate and scattered king lists, such as the Sumerian King List and the Babylonian Canon of Kings.
