Gregorian date flag and SPARQLI have been involved in a discussion on my User talk about Julian and Gregorian dates, in the flag raised from time codes. To carry out widespread checks on these flags, one would need a specialised SPARQL query, which could be applied with various side conditions (e.g. dates in an interval, country, sourcing). So, has anyone figured out how to query on Julian/Gregorian? 09:29, 14 September 2016 (UTC)) talk (Charles Matthews. For example, the following query returns all birth dates after 1930 using the Julian calendarwikibase:timeCalendarModelto query on calendar, use 09:36, 14 September 2016 (UTC) Jura--- Try the "before year 1 query" on property talk pages. You can change the date range. All dates on WQS are Gregorian.
