Motivation[edit]
Wikidata (and myself) still struggle with this, but this property would allow simplified checks and retrieval from through P17. As a separate property it can include multiple values for countries. A qualifier can be used to indicate whatever calendar was used before. Items for detailed articles can be linked with "statement is subject of" (Add your motivation for this property here.) --- Jura 10:06, 1 September 2019 (UTC)
Discussion[edit]
Support would help a lot - Salgo60 (talk) 21:29, 2 September 2019 (UTC)- Support but I'm adjusting the proposed English label to match adoption of the Gregorian calendar (Q18350297). Just "Gregorian calendar" doesn't sound like a property label. ArthurPSmith (talk) 18:49, 3 September 2019 (UTC)
- I'm not sure. Maybe "start date"? I had removed "adopted" from the description and replaced it with "first used" to avoid a possible ambiguity with the day before, the date the adoption was decided and/or the last time the previous model calendar system was regularly used (generally the previous day except for e.g. Sweden). --- Jura 17:18, 4 September 2019 (UTC)
- "Gregorian calendar start date" would be fine as the label too. ArthurPSmith (talk) 20:43, 4 September 2019 (UTC)
