author « (XXXX–YYYX) »

Alexander Harkavy (1863–1939) displays both day of birth and days of death for the author.

Is the indication « (1863–1939) » generated automatically from « Common Knowledge » ? If not how can it be added for other authors?

If yes does it generate immediately or how long would it take normaly?

Please feel free to post any related link here if such desciptions / discussions already available.

yes the dates are generated from common knowledge. One living author complained about their birth date being displayed and all living authors birth dates were removed. I thought that was rather silly.
