It is a day to honour fathers and father figures, such as grandfathers and fathers-in-law. Many people make a special effort to visit their fathers or to send them a card or gifts.
Father's Day is not a public holiday and it falls on 3rd Sunday of June. Public transport systems run to their normal timetables, however pubs and restaurants may be busy, as people take their fathers out for a meal to celebrate.
