Investigate Date Formatting Issues #42

Open thomersch opened 3 years ago

The whole date range formatting is kind of a faff: The templates are difficult to read and the i10n situation is a little bit complex. But besides the conventions, there are some proper bugs:

For fr-(FR|BE) it does not capitalize the months: "12 octobre"
For de-AT it does say "Januar" instead of "Jänner"

At least those two need to be investigated and fixed. I assume the Django API is being misused in OSMCAL code or Django itself has some issues.

Apparently, the french capitalization issue is fixed by using "E" instead of "F" in the date template (fixed in https://github.com/thomersch/openstreetmap-calendar/commit/e9359f92635f43116ef003bbcc47c460e9bfa6f5).

We should consider using Babel for formatting dates, since it seems to have the functionality to format date/time ranges.

Agreed. YMD format is being used instead in some Languages (e.g. dz, en-CA/fr-CA, hu, lt, ja, ko, mn, zh, etc), so they are incompatible with current syntax.

I have done a little bit in that direction (e.g. "2021年4月22日 12:00 德国（柏林）时间"), but Babel still needs some glue code if we want to use it. A particular problem are multi-day events with times, e.g. "20 Aug 2029, 17:00:00 – 22 Aug 2029, 19:00:00 UTC", where neither month formatting nor time formatting are well-controllable. For detail pages I would want to show full-width months (e.g. "August"), but skip the seconds altogether. This will require some more hacking around, but I haven't given up yet!
