The word is simply built from 'das Jahr' (the year) and 'die Zahl' (the number). The 'es' in the middle is a linking element that connects the two words. So it literally means 'the number of the year.'

You use the word 'Jahreszahl' (year number) when talking about the number itself. To date an event in a specific year, you usually say 'im Jahr ...' (in the year ...) or simply the number.

'das Jahr' and 'die Jahreszahl' are both connected with chronology, but they do not mean the same thing. 'Ein Jahr' is a period of time, meaning twelve months or a specific period such as a school year. 'Eine Jahreszahl' is the number used to name a specific year, for example 1990 or 2024. Learners may confuse the words because both talk about years. If you are talking about duration, use 'Jahr'. If you mean the number on a document, monument, or in a date, 'Jahreszahl' fits.
