Gregorian Calendar - Week

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:

    The press, that goiter of the world, swells up with the desire for conquest and bursts with the achievements which every day brings. A week has room for the boldest climax of the human drive for expansion.
    Karl Kraus (1874–1936)

    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)

    A friend and I flew south with our children. During the week we spent together I took off my shoes, let down my hair, took apart my psyche, cleaned the pieces, and put them together again in much improved condition. I feel like a car that’s just had a tune-up. Only another woman could have acted as the mechanic.
    Anna Quindlen (20th century)
