The ISO calendar weeks for 2019 are defined according to the international ISO standard. That is, each calendar week starts on Monday and ends on Sunday. Even during the change of year, a new calendar week starts on Monday and ends on Sunday. The ISO standard specifies that the majority of the first calendar week (i.e., at least four days) must lie in the new year.

The "American" calendar weeks for 2019 are used in the USA, Canada and most Latin American countries, Australia, Japan, Israel, South Korea and others. Unlike the otherwise internationally standardised ISO weeks, the American calendar weeks start on Sundays instead of Mondays and end on Saturdays. However, the first calendar week always begins on the 1st of January and the last always ends on the 31st of December. These two weeks can have fewer than seven days. There are always 53 calendar weeks, except in a leap year where 31st December is a Sunday. As a result, such a year will have 54 calendar weeks.
