?The age of menopause for women who are 60 years old, and for women who are not 50 lunar years old.
(Zanjani: If she is sure that she is 60 or has doubts about it, if the bleeding starts during the days of menstruation or one or two days before that, or if her blood has the characteristics of menstruation, it is considered menstruation.)
Khoei, Tabrizi, Wahid, Shahroudi
? After 60 lunar years, the blood that they see is istihaza. Between 50 and 60 years, if the blood had the characteristics of menstruation or was during the days of menstruation, she should combine the acts of menstruation and the acts of mustahaza, as a precaution.
Sistani
?Menopause occurs with respect to menstruation upon reaching the age of 60 in both Sayyidah and non-Sayyidah, and the recommended precaution for non-Sayyidah women between the ages of 50 and 60 is that if she has the characteristics of menstruation, she should combine the characteristics of menstruation with the acts of mustahazah. The ruling on menopause in the waiting period that causes the waiting period to end is, according to Azhar, limited to fifty years.
Bahjat
?A Sayyidah becomes menopausal upon reaching the age of 60, and a non-Sayyidah between the ages of 50 and 60, if she is sure that the blood she sees is menstruation, she should apply the rulings of menstruation.
Khamenei
?It is necessary to reflect and be cautious in determining the exact age limit for menopause. Women can refer to the Jame’e-e-Sharaiti Mujtahid, who has a specific fatwa on this issue.
Makaram
?The age of menopause is absolutely the completion of fifty lunar years unless the blood has the characteristics of menstruation and its conditions.

How to calculate the lunar year with the solar year?
50 lunar years = 48 years and 6 solar months
60 lunar years = 58 years and 77 days minus 12 hours.
