International Mothers Day May 13th
In the UK and Ireland the original event had nothing to do with mothers at all and it was a day for Christians to visit their "mother" church.
In the past, domestic servants were given the day off to return to their hometown and worship with their families.
On their way home, these youths would pick wild flowers to place in the church - or give to their mums.
The US event was launched separately but was dedicated entirely to mothers.
