Sunday (IPA: /ˈ ˈsʌndi or sʌndeɪ,/ Listen (help·info)) is the day of the week between Saturday and Monday. Sunday is traditionally associated with Church attendance. In the Jewish law, Sunday is the first day of the Hebrew calendar week. In many Christian traditions it is considered the 'Christian Sabbath', which is a change from the seventh day, Jewish Shabbat.[1] For many Christians it began to take the place of Jewish Shabbat in as the day set apart for the public and solemn worship of God. Sunday is considered the first day of the week in some countries, including the United States and Japan, although today many countries such as the United Kingdom regard Sunday as the seventh day, at least in the working week and the civil week.[2] Sunday is considered a non-working day in many countries of the world, and is part of "the weekend". Countries predominantly influenced by Jewish or Islamic religions have Friday or Saturday as a weekly non-working day instead. The Gregorian calendar repeats every 400 years, and no century starts on a Sunday. The Jewish New Year never falls on a Sunday. Only those months beginning on a Sunday will contain a Friday the 13th.
