When does the waiting period (iddah) for a woman whose husband died on 18/2/2020 end?

The waiting period (iddah) for a woman whose husband has died, if she is pregnant, ends when she gives birth. If she is not pregnant, her waiting period is four months and ten days. The waiting period is calculated in Hijri months. So, if a woman's husband passed away on the 24th of Jumada al-Akhirah 1441 AH (February 18, 2020), her waiting period would end on the 3rd of Dhul-Qa'dah 1441 AH (June 24, 2020).
