A memorial service can take place immediately following a cremation or burial but are usually held days, weeks or even months later. With a memorial service, which is usually similar to a funeral service, there is more flexibility over where and when the event is held. A benefit of a memorial service is that you might be able to accommodate more of those wishing to attend, especially if held on a weekend rather than during the week. Another advantage is that there are no time constraints and a memorial service can therefore last longer than ceremonies are often limited to in crematorium chapels.
As memorial services often involve more people attending it is an opportunity for more people to contribute and ceremonies usually have more of a celebratory and upbeat feel to them. With many people now choosing to have a direct cremation, memorial services are becoming more popular as they still give the opportunity for people to come together to share memories and to celebrate a person's life.
