My husband passed away on Saturday, August 27, 2022, so when does the waiting period (iddah) end?

A woman whose husband has died observes an 'iddah (waiting period) of four months and ten days, calculated by the lunar months. If the husband dies during the middle of a month, she completes the remainder of that month, then observes 'iddah for three months calculated by the lunar months, and then completes the remainder of the month following those three months until the 'iddah totals thirty days, to which ten days are added. Thus, if the husband dies on the twenty-ninth of Muharram, her 'iddah ends on theth tenth of Jumada al-Akhirah.
