If our Hebrew calendar is based on Rav Adda's calculations, why is birkat ha-chama based on Mar Shmuel's calculations? Also, why don't we say shehechiyanu when we say birkat ha-chama?

Kiddush Lavana is a time of joy, and many of its halachot and customs reflect this. So can a mourner say Kiddush Lavana? We are supposed to enjoy the light of the moon as part of the reason for the blessing, but do we look at the moon while reciting Kiddush Lavana?
