Is it so good that the wedding day is mom's 60th birthday?

Yes, this is a double happiness. In my opinion, you think these things are very complicated, or you are greatly influenced by the constellation theory in Hong Kong and Taiwan. Isn't it just getting married? Is it necessary to consider so much? As long as everyone can arrange the time, as long as it is an auspicious date, there is no need to make it so complicated. Marriage is a combination of love, not superstition.
