Alright, `DateHelper.scala` is backend and `ui/lib/src/i18n.ts` is frontend If this logic has to stay completely separate, I'll just add translations for `DateHelper.scala`

#17706

> ci/aux will ask you to change the commit name. We need something like "all: fix typos" to follow the linter recommendation. Ok, @tarasmadan, I changed the title

#6100

These too https://github.com/lichess-org/lila/blob/ab7d1747cea2c49259bb2a70bb46ced5c1ba4520/modules/ui/src/main/helper/DateHelper.scala#L115-L122 https://github.com/lichess-org/lila/blob/ab7d1747cea2c49259bb2a70bb46ced5c1ba4520/modules/ui/src/main/helper/DateHelper.scala#L125-L128

I'll take care of these, unless someone else does it before me
