In my template I sort by months my post like this:
{{ range (where site.RegularPages "Type" "in" site.Params.mainSections).GroupByDate "January, 2006" -}}
<h1>{{ .Key }}</h1> // output: March, 2022
{{ range (where .Pages ".Params.unlisted" "!=" "true") }}
<div>{{ time.Format "02 January" .Date }} - {{ .Title }}</div> // output: 01 Mars - This is the title of my post
{{ end }}
{{ end }}
For every post the time.Format localized my date in my language (here in French).
But the title witch is group by month is still in English (here it's the h1). How can I format my {{ .Key }} so it can be localized in my own language and show "Mars, 2022" instead of "March, 2022" ?
