Week
In conjunction with the system of months there is a system of weeks. A physical or electronic calendar provides conversion from a given date to the weekday, and shows multiple dates for a given weekday and month. Calculating the day of the week is not very simple, because of the irregularities in the Gregorian system. When the Gregorian calendar was adopted by each country (but not Alaska), the weekly cycle continued uninterrupted. For example, in the case of the few countries that adopted the reformed calendar on the date proposed by Gregory XIII for the calendar's adoption, Friday, 15 October 1582, the preceding date was Thursday, 4 October 1582 (Julian calendar).
Opinions vary about the numbering of the days of the week. ISO 8601, in common use worldwide, starts with Monday=1; printed monthly calendar grids list Mondays in the first (left) column of dates and Sundays in the last. Software often starts with Sunday=0. In the United States, it's generally the case that Sunday=1, with Sundays shown in the left column of a monthly calendar page.

Famous quotes containing the word week:
“And although he had given himself a week to do it in and had told the landlady that he had finally decided to leave on Saturday, Ganin felt that neither this week not the next would change anything. Meanwhile nostalgia in reverse, the longing for yet another strange land, grew especially strong in spring.”
—Vladimir Nabokov (1899–1977)
“Pray be always in motion. Early in the morning go and see things; and the rest of the day go and see people. If you stay but a week at a place, and that an insignificant one, see, however, all that is to be seen there; know as many people, and get into as many houses as ever you can.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“My veins are filled, once a week with a Neapolitan carpet cleaner distilled from the Adriatic and I am as bald as an egg. However I still get around and am mean to cats.”
—John Cheever (1912–1982)
