When is Mother's Day 2020?
This year, Mother's Day will fall on Sunday, March 22 - the fourth Sunday in Lent.
It also falls exactly three weeks before Easter Sunday, which is on April 12 this year.
What are the origins of Mother's Day?
The origins of Mothering Sunday in the UK begin in the Middle Ages, when children who had left their families to work in domestic service were allowed to go back to their home church - or "mother church" as it was known.
At first, the "mothering" aspect of the day had no link to maternal parents, as it does today.
The journey home also morphed into a spring occasion for families to reunite.
The custom then developed for children to pick flowers on the way home as a gift to their mothers.
The date also became a celebration as the fasting rules of Lent were relaxed to allow revellers a long-awaited feast.
So it also became known as Refreshment Sunday, Simnel Sunday - after the simnel cakes traditionally baked on the day - and Pudding Pie Sunday to some.
How did "Mothering Sunday" become "Mother's Day"?
The American festival of Mother's Day, which is held later in the year and has no religious connotations, drifted across the Atlantic.
So soon Mothering Sunday became more popularly known as Mother's Day in the UK.
The American day was created in 1907 by Anna Jarvis, who held a memorial for her mother Ann Jarvis, a peace activist who treated wounded soldiers in the American Civil War.
Her daughter campaigned for a day to honour the role played by mothers.
The idea gained such traction that by 1911 all US states took on the holiday.
In 1914, President Woodrow Wilson declared Mother's Day a national holiday.
When is Father's Day 2020?
Father's Day 2020 in the UK falls on Sunday, June 21.
The celebration is always held on the third Sunday of June to honour fathers.
It is thought the festival may have originated in pagan sun worship with some branches of the religion seeing the Sun as the father of the universe.
