GitHub user FrancescoCastaldi created a discussion: How to set Italian month
abbreviations (%b) in table chart date format?
## Question
I'm using Superset 3.x with table charts that display dates using the format
`%d - %b` (e.g., "15 - Jan", "20 - Feb"). The abbreviated month names are
showing in **English** instead of **Italian**.
### Current Setup
- Superset 3.x with Docker deployment
- Table chart with date column formatted as `%d - %b`
- `BABEL_DEFAULT_LOCALE` is set to `"it"` in config
- UI language is correctly set to Italian
### What I've Found in the Codebase
In `superset/config.py`, there's a `D3_TIME_FORMAT` config that can override
the default d3 locale:
```python
# Override the default d3 locale for time format
D3_TIME_FORMAT: D3TimeFormat = {}
```
With a structure that includes `months` and `shortMonths` arrays.
### Questions
1. **How do I set Italian month abbreviations for the `%b` format in table
charts?**
2. Is setting `BABEL_DEFAULT_LOCALE = "it"` sufficient, or do I also need to
configure `D3_TIME_FORMAT` with Italian `shortMonths`?
3. If `D3_TIME_FORMAT` is needed, what's the correct configuration? For example:
```python
D3_TIME_FORMAT = {
"dateTime": "%x, %X",
"date": "%-m/%-d/%Y",
"time": "%-I:%M:%S %p",
"periods": ["AM", "PM"],
"days": ["domenica", "lunedì", "martedì", "mercoledì", "giovedì",
"venerdì", "sabato"],
"shortDays": ["dom", "lun", "mar", "mer", "gio", "ven", "sab"],
"months": ["gennaio", "febbraio", "marzo", "aprile", "maggio", "giugno",
"luglio", "agosto", "settembre", "ottobre", "novembre", "dicembre"],
"shortMonths": ["gen", "feb", "mar", "apr", "mag", "giu", "lug", "ago",
"set", "ott", "nov", "dic"]
}
```
4. Does this override apply globally to all charts, or only to new charts?
5. Is there a per-chart or per-column way to set the locale, or is it only a
global config?
