What is a year?

Year – a conventional unit of time, equal to 365 days (days) or 366 (leap year, which is divided by 4). This is the time during which the Earth completes its one revolution around the Sun. Abbreviated Russian designation: city, in English – y or yr.

A year consists of four seasons: winter, spring, summer, autumn containing 12 months. The word “year” comes from the Old Slavonic “god” and means “time, year” or “goditi” – “to please, satisfy.” There are such concepts as a millennium – 1000 years, a century – 100 years, a decade – 10 years, half a year – 6 months, a quarter – 3 months.

What is a week?

A week is a unit of time equal to seven days (days). Abbreviated Russian designation: week, in English – wk. It consists of Monday, Tuesday, Wednesday, Thursday, Friday, Saturday and Sunday. The calendar week starts on Monday and ends on Sunday. Translated from ancient Greek, “week” means “non-working day” or “holiday”.

The combination of seven days into one week is associated with the period of revolution of the Moon around the Earth, which is known to be approximately 28 days. 28 was divided by 4, by the number of moon phases available (new moon, waxing moon, full moon, waning moon), resulting in 7 days.
