BH thanks. please consider a tzadikim yahrzeit/hiloula check box, I know it'd be a lot of work to track down all those dates but G-d should help your team. shavua tov, G-d bless you all. thank you.

another idea i thought of to improve the already amazing hebcal is adding yahrzeit/hiloula check box for well know tzadikim (Moshe rebeinu, Hida, Rambam, Arizal, Rama, Rav Kook, ROY, etc.) עליהם השלום

BH, thanks so much for this chizuk

Shalom. thanks. yes,  "Tevet / Sh'vat 5784" next to or under the Gregorian month would be helpful
