A '''common year starting on Monday''' is any non-[[leap year]] (i.e., a year with 365 days) that begins on [[Monday]], [[1 January]], and ends on [[Monday]], [[31 December]]. Its [[dominical letter]] hence is '''G'''. The most recent year of such kind was [[2018]], and the next one will be [[2029]] in the [[Gregorian calendar]], or likewise, [[2019]] and [[2030]] in the [[Julian calendar]], see [[#Applicable years|below for more]]. This common year is one of the three possible common years in which a century year can begin on and occurs in century years that [[Century common year|yield a remainder of 300 when divided by 400]]. The most recent such year was [[1900]], and the next one will be 2300.

Any common year that starts on Monday has two [[Friday the 13th]]s: those two in this common year [[April 13|occur in April]] and [[July 13|July]].{{Globalize-inline|date=May 2022}}
From July of the year in this type of year to [[September 13|September]] in the year that follows this type of year is the longest period that occurs without a Friday the 13th, unless the following year is a [[leap year starting on Tuesday]], in which case the gap only 11 months, as the next Friday the 13th is already in [[June 13|June]].

This type of year has three instances of [[Tuesday the 13th]]: in February, March and November. [[Leap years starting on Thursday]] have this characteristic in January, April and July.

This year has four months (April, July, September and December) which begin on a weekend-day.
