Monday the first day of the working week after the weekend.
The English word Monday was derived in approximately 1200 from monedaei, which originated in Old English (around 1000) mondaeg meaning literally the day of the moon, moon day.
Similar words existed in other european languages, such as Old Frisian monadeig, Middle Low German and Middle Dutch manendach, Old High German manetag , and Old Norse manadagr. The Germanic term is a Germanic interpretation of Latin lunae dies ("day of the moon").
The international standard, ISO 8601, defines Monday as being the first day of the week, even though Sunday is traditionally regarded as the first day of the week.
Following the industrialisation of business, the working week became formalised as Monday to Friday, the term 'weekend', first recorded in 1878, is defined in Webster's Ninth New Collegiate Dictionary (1983) as 'the period between the close of one working or business or school week and the beginning of the next', putting Monday at the start of the week.
In Middle Eastern countries, however, the beginning of the working week is usually Saturday (Thursday and Friday are observed as the weekend). In Israel, Sunday is the first day of the workweek. Friday is half a work day and Friday night and Saturday are the Sabbath.
