Its defiantly called Mothering Sunday
Mothering Sunday falls on the fourth Sunday in Lent, exactly three weeks before Easter Day, and this year (2019) it’s the 31st March.
Once observed as a day on which people, servants and apprentices were allowed to take a day off and go home to visit their mothers and "mother" church, it has also become an occasion for honoring the mothers of children and giving them presents.
Unfortunately, it is increasingly being called Mother’s Day, although that name properly belongs to the American holiday which is quite distinct from the original Mothering Sunday.
In the UK and the Republic of Ireland, Mothering Sunday is celebrated in a similar way as Mother's Day is celebrated in the US.
Two other names are used for this day, (well three, see further down) the first being “Refreshment Sunday”.
This is the point during the 40 days of their lent fasting that people can ease up and refresh themselves by feasting. The practice of fasting has become more popular, perhaps a way of easing up of things like chocolate, cake or alcohol, but roots based in replicating the sacrifice of Jesus Christ's journey into the desert for 40 days.
The Second name that this Sunday is known by is “Rose Sunday”. (or Laetare Sunday)
(Bit of background info here)
During the Churches year, specific colours are used in the robes or vestments that vicars wear, and in the hangings such as on the alter or pulpit, and on this particular Sunday this happens to be Rose.
Other colours may be used during the churches year, Green Mauve White Red, however this Sunday and Gaudete Sunday, which is the 3rd Sunday in Advent (15th December 2019) are the only 2 Sundays when Rose/Pink will and can be worn, so get your Pink socks, jumpers scarves etc out and embrace the Rose, oh and Happy Mothering Sunday
