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:
“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)
“How pleasant is Saturday night,
When I’ve tried all the week to be good,
And not spoke a word that was bad,
And obliged everyone that I could.”
—Nancy Sproat (1766–1827)
“For most visitors to Manhattan, both foreign and domestic, New York is the Shrine of the Good Time. “I don’t see how you stand it,” they often say to the native New Yorker who has been sitting up past his bedtime for a week in an attempt to tire his guest out. “It’s all right for a week or so, but give me the little old home town when it comes to living.” And, under his breath, the New Yorker endorses the transfer and wonders himself how he stands it.”
—Robert Benchley (1889–1945)
