What is Common year?
A '''common year''' is a [[calendar year]] with 365 [[day]]s. It is a year that is not a [[leap year]]. This means a common year has 52 [[week]]s and one day. So if a certain year started on a Monday, the following year will start on a Tuesday. Stated differently, a common year always begins and ends on the same day of the week (for example, in 2023, January 1 and December 31 fell on a Sunday). In common years, [[February]] has exactly four weeks, so [[March]] begins on the same day of the week. [[November]] also begins on this day. For example, if February 2023 began on a [[Wednesday]], then March would begin on a Wednesday as well. November follows the same characteristic. In a common year, the corresponding months are January and October; February, March, and November; April and July; as well as September and December. No month corresponds to May, June nor August. In the [[Gregorian calendar]], 303 out of every 400 years are common years. In the [[Julian calendar]], 300 out of every 400 years were common years. All the other years are special and known as [[leap year]]s. == Years == *[[2000]], a [[century leap year]], began on a [[Saturday]]. *[[2001]] began on a [[Monday]]. *[[2002]] began on a [[Tuesday]]. *[[2003]] began on a [[Wednesday]]. *[[2004]], a [[leap year]], began on a [[Thursday]]. *[[2005]] began on a [[Saturday]]. *[[2006]] began on a [[Sunday]]. *[[2007]] began on a [[Monday]]. *[[2008]], a [[leap year]], began on a [[Tuesday]]. *[[2009]] began on a [[Thursday]]. *[[2010]] began on a [[Friday]]. *[[2011]] began on a [[Saturday]]. *[[2012]], a [[leap year]], began on a [[Sunday]]. *[[2013]] began on a [[Tuesday]]. *[[2014]] began on a [[Wednesday]]. *[[2015]] began on a [[Thursday]]. *[[2016]], a [[leap year]], began on a [[Friday]]. *[[2017]] began on a [[Sunday]]. *[[2018]] began on a [[Monday]]. *[[2019]] began on a [[Tuesday]]. *[[2020]], a [[leap year]], began on a [[Wednesday]]. *[[2021]] began on a [[Friday]]. *[[2022]] began on a [[Saturday]]. *[[2023]] began on a [[Sunday]]. *[[
