Hi,

Developing a style where I need to add date ranges for exhibition catalogues I noticed the following, in Word and LibreOffice (24.8.2.1, Win11)

The data range is entered like so in extra:

event-date: 1999-11-05/2000-03-19

but comes out like this (see the odd spacing for the 2nd date):

05. November 1999–19. .März .2000

I have this like so in my CSL style and it works for a single date just fine:
<date variable="event-date">
<date-part name="day" form="numeric-leading-zeros" suffix=". "/>
<date-part name="month" suffix=" "/>
<date-part name="year"/>
</date>
