Motivation edit

At Help:Dates#Property_pairs_for_time_periods, there is a list of such pairs. I think it would be good to add it as structured data into Wikidata as well. Please don't hesitate to improve the description and even the label (Add your motivation for this property here.) --- Jura 12:32, 20 November 2020 (UTC)[reply]
