A working day is a day on which a period of time is actually taken up by work, which in the strict sense usually employed is meant. Often the working day is a business day and the daily working time is not always of the same duration.
In the ancient cultures and even during the Middle Ages, the difference between day and night was the light and dark and therefore of far greater importance than in most contemporary societies, the pace of life has become equal displaced by artificial means.
The light of day determines not only the concept of the social and personal day, but also the working day. In the Middle Ages, but also to the early 19th century - and in many parts of the world outside Europe until today - is working all day from " dawn to dusk ", the working day - as the working day - is up to 16 hours. Until just the 20th century servants and servants were additional one to three unpaid work days, so-called shit days imposed in southern Germany and Austria, which should compensate for the time taken by them for the performance of bowel movements during the agreed job.
The day's work is synonymous with the work done here. To date, it is the duty of the employee, rested to show up for work, so one night as a sleep time to the obligations of the working people. Only the fact that legal rules on the permitted maximum daily working time ( working time laws) are introduced, a window of time after work to do, which needs to be used either for work or for rest. Mid-20th century is reduced in the industrially developed countries, the daily working time of 10 mostly 8 hours, and the considerable period of time given the name Leisure as "free " time between day and night.
Today, the word of the day about half-time work, the question arises as working mainly in some idioms to express, "How was the day? " ( Even if the child lunch comes home ), " be satisfied with his day's work ," and the " Feierabend " as the end of working hours in the late afternoon.
Even today, many holidays are celebrated on the eve, such as Christmas Eve or Nicholas Eve, because in some previous calendars in Europe, the new calendar began similarly as in Jewish and Islamic calendars not only at midnight, but already with the local dusk, and so a holiday with the celebration evening.
In the context of globalization and time- immediate worldwide communication, the question of the day time in other time zones is up to date. The shift of the clear day to the subjective day when traveling by air produces the jet lag.
