My friend is married and can't go. I dragged my friend with a red envelope. I want to call or send a message to bless you. When is the right time to call?

Call ahead, preferably early. I think it is more appropriate to call two or three days in advance. I want to know what customs you have there. On my side, all the relatives who have traveled a long way to get married have come, basically the day before, unless they came by car within half an hour on the wedding day. So the day before and on the wedding day, the bride and groom are super busy. Although they don't eat or drink, they must be greeted by all their relatives and friends, otherwise it will be impolite. On the wedding day, because of the ceremony, the best man and bridesmaid followed back and forth, and the mobile phone was basically turned off. One is afraid that the sudden ringing of the mobile phone will affect the effect of the ceremony, and the other is afraid that something will affect the mood of the couple.

So it is more appropriate to call two days in advance, or you can say in detail that you can't go. I'm very sorry.
