I have downloaded my father's Yahrzeit dates on the Hebcal calendar for many years.. My father passed on the 8th of kislev. in 1999. In 2019 it listed the Yahrzeit date of Sat, November 13, 2021 as the correct date.. I just checked on a more recent Hebcal Jewish calendar and his Yahrzeit date is now listed as Friday, November 12, 2021. Can you help explain this to me? I am very confused.
Thanks so much!
