ISO 8601
The calendar sets periods of time by combining days into weeks, weeks into months and months into years. The international standard ISO 8601 is used to display the date and time. The German-language calendar is not an exception. Since 1976 every week has started on a Monday and ended on a Sunday. In countries such as the USA, Mexico, Australia and Canada the weeks start with Sunday as the first day of the week and end on Saturday. Other important rules of the ISO 8601:

• A new calendar week (week number) always begins on Monday.
• There are no incomplete calendar weeks; every week has exactly seven days.
• The first calendar week starts with the first four days of the new year.
• The fourth of January is always in the first WN.

the leap year
A standard year has 52 weeks if it is not a leap year. When a normal year starts on a Thursday and also ends on one, it is 53 weeks long. A leap year also consists of 53 calendar weeks, beginning either on a Wednesday and ending on a Thursday or starting on a Thursday and ending on a Friday. Why does a leap year have one day more than a normal year? The earth rotates 365 days and 6 hours around the sun, which is longer than the standard calendar year. This would be noticed at some point. Christmas would end up being sometime in the summer. To compensate for this inaccuracy, an extra day - February 29 - was introduced every four years. In addition, years that are divisible by 100 but not by 400 are not leap years, as is the case with 1700, 1800, and 1900.

The names of the weekdays
The Romans named the days after their gods, the seven ancient planets (Sun, Moon, Mars, Mercury, Jupiter, Venus and Saturn). The Romans considered the sun and the moon planets as well. The Germanic peoples later translated each Roman god from Latin into Germanic.

Monday Monday is named after the Roman goddess Luna (lat. dies lunae) and the Germanic god Mani.

Tuesday Tuesday comes from the name of the Roman god of war Mars (Lat. dies Martis) and the Germanic god of war Tyr.

Wednesday Wednesday is also referred to as midweek. Its name is derived from the Roman god Mercuris (lat. dies mercoledi) and the Germanic god Wotan.

Thursday Thursday is named after the Germanic god of thunder Thor and the Roman god Jupiter (lat. dies iovis).

Friday Friday is derived from the Roman goddess of beauty Venus (lat. dies veneris) and the Germanic goddess of love and marriage Freya.

Saturday Saturday is derived from the Jewish Sabbath. The Romans named the day after the Roman god of seed Saturn (lat. dies saturni).

Sunday Sunday is named after the sun god Sol (lat. dies solis). This day and god were extremely important to the ancient Romans. Sunna was the Germanic sun goddess.

The current calendar week
The calendar weeks serve different purposes. Professionals working in the business sector set up their business appointments based on the calendar weeks. Hence business persons are best-informed when it comes to details about the current week number. The rule of thumb to calculate the week number is based on the number of months from January to the last month multiplied by 4 plus the number of weeks in the current month. Unfortunately the right week number can be off by up to 2 weeks. The calendar has become a necessity to us all. Almost everyone uses one, whether as a notebook or app on their mobile phone. This way we don’t forget important dates such as holidays, annual leave or exam weeks. Without these helpers, many of us would be lost.
