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:
“[When asked: “If women voted, would they not have to sit on juries?”:] Many women would be glad of a chance to sit on anything. There are women who stand up and wash six days in the week at 75 cents a day who would like to take a vacation and sit on a jury at $1.50.”
—Anna Howard Shaw (1847–1919)
“Jesus would recommend you to pass the first day of the week rather otherwise than you pass it now, and to seek some other mode of bettering the morals of the community than by constraining each other to look grave on a Sunday, and to consider yourselves more virtuous in proportion to the idleness in which you pass one day in seven.”
—Frances Wright (1795–1852)
“Some days your hat’s off to the full-time mothers for being able to endure the relentless routine and incessant policing seven days a week instead of two. But on other days, merely the image of this woman crafting a brontosaurus out of sugar paste and sheet cake for her two-year-old’s birthday drives a stake through your heart.”
—Melinda M. Marshall (20th century)
