I brought that up 4 years ago in https://meta.discourse.org/t/its-not-possible-to-correctly-translate-topic-stat-sentence/18359
This could be a great #starter-task if someone wants to fix the translation.
Iād recommend replacing the existing translation with 4 new ones:
topic_stat_sentence_day
topic_stat_sentence_week
topic_stat_sentence_month
topic_stat_sentence_year
