How our calendar was made: Romans, Julius Caesar and Pope Gregory, sentence 18

In the Gregorian calendar a century year is a leap year only if it divides exactly by 400, so 2000 was a leap year but 1900 was not.

Who acts: century year, calendar, 2000 · What happens: be, divide · To what, where: leap year, Gregorian calendar

This is a sentence of the lesson «How our calendar was made: Romans, Julius Caesar and Pope Gregory» of the world course of Mova's primary school. The page gives its syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause: who acts (century year, calendar, 2000), what happens, when and where, as Mova's frames read it from the tree.
