Of course this varies depending on your wishes, but in general the following applies:
Children’s Welcome Ceremony: so that it doesn’t get too long for the children, the ceremony is usually
around 20 – 35 minutes
Wedding Ceremony: usually around 45 minutes
Funeral: The day is difficult enough for those who mourn and does not have to be unnecessarily prolonged. Therefore, a Funeral Ceremony only lasts about 20 minutes. In addition, in the cities you can often only book the mourning hall for 20 minutes
