Troubleshooting

If clock module is disabled at startup with locale::facet::_S_create_c_locale
name not valid error message try one of the following:

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:

1.: Use "WenQuanYi Zen Hei Mono" which is provided in most Linux distributions
2.: Try different font sizes and find best for you. size = 9pt should be fine
3.: 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>",
	"calendar": {
		"mode"          : "year",
		"mode-mon-col"  : 3,
		"weeks-pos"     : "right",
		"on-scroll"     : 1,
		"on-click-right": "mode",
		"format": {
			"months":     "<span color='#ffead3'><b>{}</b></span>",
			"days":       "<span color='#ecc6d9'><b>{}</b></span>",
			"weeks":      "<span color='#99ffdd'><b>W{}</b></span>",
			"weekdays":   "<span color='#ffcc66'><b>{}</b></span>",
			"today":      "<span color='#ff6699'><b><u>{}</u></b></span>"
		}
	},
	"actions": {
		"on-click-right": "mode",
		"on-click-forward": "tz_up",
		"on-click-backward": "tz_down",
		"on-scroll-up": "shift_up",
		"on-scroll-down": "shift_down"
	}
},
