# Troubleshooting
If clock module is disabled at startup with locale::facet::\_S\_create\_c\_locale ++
name not valid error message try one of the followings:
- check if LC_TIME is set properly (glibc)
- set locale to C in the config file (musl)
The locale option must be set for {calendar} to use the correct start-of-week, regardless of system locale.
## Calendar in Chinese. Alignment
In order to have aligned Chinese calendar there are some useful recommendations:
. Use "WenQuanYi Zen Hei Mono" which is provided in most Linux distributions
. Try different font sizes and find best for you. size = 9pt should be fine
. In case when "WenQuanYi Zen Hei Mono" font is used disable monospace font pango tag
Example of working config
```
"clock": {
"format": "{:%H:%M}  ",
"format-alt": "{:%A, %B %d, %Y (%R)}  ",
"tooltip-format": "\n<span size='9pt' font='WenQuanYi Zen Hei Mono'>{calendar}</span>",
