The electronic invitations are usually sent out a month in advance, and sent out a second time 15 days before the wedding to remind guests again and do a good job of counting the number of people attending the wedding.
Couples should send out e-invitations at least one month before the wedding date. Especially during the wedding season (e.g. Golden Week). This problem needs to be transposited, when guests receive the e-invitation card of the couple, the first thing to consider is whether they have time to attend the wedding, if so, but also consider who to attend the wedding. During Golden Week, a friend may receive invitations from several people on the same day. If your e-invitation is sent out early and arrives before another friend's e-invitation, the guest may agree to attend your wedding, and because he has already committed to you, he may not attend another wedding.
Couples should send a second e-invitation 15 days before the wedding date to remind guests and count the number of guests attending their wedding. New people must call the guests or various ways to give implementation. Because the exact number of participants is the basis for ensuring the "input and output" of new people. The new couple can also increase or reduce the number of spare tables according to the number of statistics, and the hotel finally implement the official number of diners.
