Feature #863

Updated by Alexander Watzinger almost 7 years ago

At the moment it's not possible to enter BC date. It would be good if dates back to unitl -4713 (PostgreSQL timestamp limit) could be entered. 

 *Update*: Solved BC dates using the astropy library. There are some changes: 

 - year values possible from 4173 BC to 9999 AD 
 - missing values are substituted with 1 (e.g. if only the year 2018 was entered it becomes 2018-01-01) 
 - extensive We mostly likely need additional date validation was added (e.g. a begin date cannot be after an end date) 
 libraries. Maybe py-ephem?
