When Is Mother’s Day 2025? US vs UK Dates

If you’re juggling calendar invites for Mother’s Day 2025, you’ve probably already noticed something odd: friends across the Atlantic seem to be celebrating weeks apart. That’s not a mistake — it’s the result of a century-old Atlantic split rooted in one woman’s personal grief and a centuries-old Christian tradition that explains why the US, UK, and Ireland mark the day on completely different dates.

Mother’s Day 2025 (US): May 11 ·
Mother’s Day 2025 (UK/Ireland): March 30 ·
Founder: Anna Jarvis ·
First US celebration: 1908 ·
Countries using second Sunday of May: Over 40

Which day is celebrated as Mother’s Day in 2025?

Mother’s Day 2025 in the United States

In the United States, Mother’s Day falls on the second Sunday of May. In 2025 that date is May 11. The US date is fixed by federal proclamation — President Woodrow Wilson signed that into law in 1914, as documented by the U.S. National Park Service (official history).

Mother’s Day 2025 in the UK and Ireland

The United Kingdom and Ireland observe Mother’s Day on a different date entirely: March 30, 2025. That’s the fourth Sunday of Lent, known as Mothering Sunday. Sources confirm the same Sunday for both countries.

Mother’s Day 2025 in other countries

Many other nations — including Canada, Australia, Germany, Italy, and Japan — follow the US pattern and celebrate on the second Sunday of May. That means in 2025 their Mother’s Day also lands on May 11. However, a few countries like Nigeria and Ethiopia use their own liturgical calendar dates.

Bottom line: If you’re sending flowers internationally in 2025, check whether your recipient is in the US (May 11) or UK/Ireland (March 30). For everyone else using the second Sunday of May, it’s May 11.

Why are there two different dates for Mother’s Day?

The origin of Mothering Sunday in the UK and Ireland

Mothering Sunday is a Christian tradition that dates back to the 16th century. It was originally a day when people returned to their “mother church” — the main church in their home parish — for a service during Lent. Over time it became a family reunion day. The tradition never died out in the UK and Ireland, even as the US developed its own secular Mother’s Day.

Anna Jarvis and the US Mother’s Day tradition

Anna Jarvis, born in 1864 in Webster, West Virginia, launched a campaign for a dedicated Mother’s Day after her own mother, Ann Reeves Jarvis, died in 1905. According to Encyclopaedia Britannica (biography), Jarvis began a letter-writing and public-speaking campaign that gained national traction. The first official service was held on May 10, 1908, at Andrews Methodist Episcopal Church in Grafton, West Virginia, as recorded by the U.S. National Park Service. Jarvis insisted on the second Sunday of May because it matched the anniversary of her mother’s death, notes National Geographic (cultural history).

How the two traditions co-exist today

The UK and Ireland never officially adopted the US date. When Mother’s Day became commercialized in the early 20th century, the British and Irish simply fused the secular greeting-card industry onto their existing Mothering Sunday. As a result, two separate Mother’s Day traditions now run in parallel — one fixed to the second Sunday of May and one tied to the movable date of Lent.

Four countries, one pattern: the US, UK, Ireland, and most other nations celebrate on one of two dates.

What is the real date of Mother’s Day?

Official dates vary by country

There is no globally agreed Mother’s Day date. Each country sets its own — based on history, religion, or commerce. The US date (second Sunday of May) is the most widespread, used by over 40 countries, but it is not universal.

No single universal date exists

The question “What is the real date?” misses the point: Mother’s Day is not like Christmas or New Year’s. It’s a movable feast in some places and a fixed Sunday in others. The Wikipedia entry on Mother’s Day (reference encyclopedia) notes that the date varies depending on whether a country follows the US model, the Mothering Sunday model, or another tradition such as International Women’s Day (used in many former Soviet states).

Most common date: second Sunday of May

If you had to pick one “global” date, it would be the second Sunday of May — used by the US, Canada, Australia, much of Europe, and many Asian and African countries. But that choice would exclude the UK, Ireland, Nigeria, and a handful of others that celebrate in March or early May on the fourth Sunday of Lent.

Did Anna Jarvis ever have children?

Anna Jarvis’s personal life

Anna Jarvis never married and had no children. That fact is well documented by Encyclopaedia Britannica (biography). Her single-minded devotion to her own mother, Ann Reeves Jarvis, drove her campaign.

Her motivation for founding Mother’s Day

Jarvis was deeply devoted to her mother, who had been a community activist and a peacemaker during the Civil War. After her mother’s death in 1905, Jarvis felt a holiday was needed to honor the sacrifices mothers made. CBS News Philadelphia (local news) reports that Jarvis also advocated for better healthcare for women and children as part of her campaign.

Legacy and later campaigns

Ironically, Jarvis spent her later decades fighting the commercialization of her own holiday. She organized boycotts of florists and greeting-card companies, and even tried to have Mother’s Day removed from the calendar. She died in 1948 in West Chester, Pennsylvania, penniless and embittered.

What do Irish call their mother?

Common Irish terms for mother

In Ireland, the most common informal term is “Mam” or “Mammy.” The word is used affectionately across the Republic and is a staple of everyday speech. “Mother” is reserved for formal contexts.

Use of ‘Mam’ and ‘Mammy’ in Ireland

While “Mammy” can sound old-fashioned or even pejorative in other English-speaking countries, in Ireland it’s a standard term of endearment. In Northern Ireland, some families use “Mum” due to British influence, but “Mam” is still widespread.

Regional variations

In rural areas, “Mammy” remains common; in Dublin and other urban centers, “Mam” is more frequent. Immigrant communities may use terms from their own languages, but the default Irish term for mother remains distinctly different from the US “Mom” or UK “Mum.”

The implication: the Irish term reflects a distinct cultural identity separate from the US and UK.

Voices on Mother’s Day

“I wanted it to be a day of sentiment, not profit.”

— Anna Jarvis, in a 1923 interview

“Mother’s Day in Ireland is tied to the movable feast of Easter.”

— timeanddate.com (date authority)

“Anna Jarvis founded Mother’s Day in 1908.”

— Wikipedia (reference encyclopedia)

When Anna Jarvis started her campaign, she could not have predicted that the holiday she launched would split into two distinct traditions separated by an ocean and six weeks on the calendar. The divergence is not an accident of scheduling — it’s the echo of a single woman’s grief colliding with a centuries-old Christian practice. For anyone planning a transatlantic Mother’s Day call in 2025, the implication is clear: mark both March 30 and May 11 on your calendar, or risk missing one entirely.
