Mapped: When Is Mother’s Day Around the World? — 199 Countries, Six Date Rules

Key Takeaways

  • The 2nd Sunday of May is the global default. Roughly 110+ countries — the United States, Canada, Australia, New Zealand, China, Japan, Germany, Brazil, India, and most of Europe and Latin America — observe Mother's Day on the second Sunday of May. That falls on May 10 in 2026.
  • The Arab world celebrates on March 21. Egypt introduced an Arab Mother's Day on the spring equinox in 1956. The convention spread to Saudi Arabia, the UAE, Qatar, Kuwait, Oman, Bahrain, Jordan, Lebanon, Syria, Iraq, Palestine, Yemen, Sudan, Libya, Mauritania, and Somalia.
  • France and most of Francophone Africa wait until the last Sunday of May. France's Fête des mères falls on the last Sunday of May — May 31 in 2026. The convention spreads through Senegal, Côte d'Ivoire, Mali, Cameroon, the Congos, the Maghreb (excluding Libya), and arrived via the same channel in the Dominican Republic and Sweden.
  • Russia, Indonesia, Thailand, Norway, and Mexico all sit alone on their own dates. Russia: last Sunday of November. Indonesia: December 22 (Hari Ibu, commemorating the 1928 Women's Congress). Thailand: August 12 (Queen Sirikit's birthday). Norway: 2nd Sunday of February. Mexico: May 10, fixed (always May 10, never floated to a Sunday). UK & Ireland: 4th Sunday of Lent — March 15 in 2026.

If you grew up celebrating Mother’s Day on the second Sunday of May, you grew up with the world’s most-observed convention — but only just. Six distinct date rules cover the globe, and 30+ countries pick a date that doesn’t follow any of them. Mexico’s date is fixed at May 10 regardless of weekday. Russia’s is the last Sunday of November. Norway’s is the second Sunday of February. The Arab world settled on the spring equinox after Egypt’s 1956 reform. Indonesia commemorates a 1928 women’s congress every December 22. Thailand celebrates on the late Queen’s birthday in August. The UK still uses a date pegged to the medieval Mothering Sunday tradition that floats with Easter.

Today is May 5 — the world’s most-shared Mother’s Day is in five days, on Sunday the 10th. But for ~85 of the world’s countries, today either passed weeks ago or hasn’t arrived yet. This post maps every country’s Mother’s Day rule and unpacks why the same holiday looks so different on the calendar.

🌍 The 2nd Sunday of May — The Global Default (~110 Countries)

The largest single cluster traces directly to the United States. Anna Jarvis campaigned for a national Mother’s Day from her West Virginia home through the 1900s. Woodrow Wilson signed the proclamation establishing the second Sunday of May in 1914. Through American media, missionary networks, and post-WWII cultural export, that date became the default in:

  • North America: United States, Canada
  • Oceania: Australia, New Zealand, Fiji, Papua New Guinea
  • Most of Western Europe: 🇩🇪 Germany, 🇦🇹 Austria, 🇨🇭 Switzerland, 🇱🇮 Liechtenstein, 🇳🇱 Netherlands, 🇧🇪 Belgium (Antwerp uses Aug 15), 🇩🇰 Denmark, 🇫🇮 Finland, 🇮🇸 Iceland
  • East Asia: 🇨🇳 China, 🇭🇰 Hong Kong, 🇲🇴 Macau, 🇹🇼 Taiwan, 🇯🇵 Japan
  • South Asia: 🇮🇳 India, 🇵🇰 Pakistan, 🇧🇩 Bangladesh, 🇱🇰 Sri Lanka, 🇲🇻 Maldives
  • Most of Southeast Asia: 🇸🇬 Singapore, 🇲🇾 Malaysia, 🇵🇭 Philippines, 🇲🇲 Myanmar, 🇧🇳 Brunei
  • Most of Latin America: 🇨🇴 Colombia, 🇨🇱 Chile, 🇵🇪 Peru, 🇻🇪 Venezuela, 🇪🇨 Ecuador, 🇨🇺 Cuba, 🇭🇳 Honduras, 🇺🇾 Uruguay, 🇧🇷 Brazil, 🇵🇷 Puerto Rico
  • Much of Sub-Saharan Africa: 🇿🇦 South Africa, 🇰🇪 Kenya, 🇺🇬 Uganda, 🇹🇿 Tanzania, 🇳🇬 Nigeria, 🇬🇭 Ghana, 🇿🇲 Zambia, 🇿🇼 Zimbabwe (where US/British missionary influence dominated over French colonial)
  • Other: 🇺🇦 Ukraine, 🇨🇿 Czech Republic, 🇸🇰 Slovakia, 🇬🇷 Greece, 🇭🇷 Croatia, 🇧🇦 Bosnia, 🇲🇰 North Macedonia, 🇷🇸 Serbia, 🇨🇾 Cyprus, 🇲🇹 Malta, 🇪🇪 Estonia, 🇱🇻 Latvia, 🇹🇷 Turkey

🌷 March 21 — The Arab World’s Spring Equinox

In 1956, Egyptian journalist Mustafa Amin founded an Arab Mother’s Day, set permanently on the spring equinox — March 21. Amin’s column in Akhbar El Yom framed motherhood as a renewal symbol that fit the equinox’s astronomical meaning. Within a decade the convention spread across the Arab League:

  • 🇪🇬 Egypt, 🇸🇩 Sudan, 🇯🇴 Jordan, 🇱🇧 Lebanon, 🇸🇾 Syria, 🇮🇶 Iraq, 🇵🇸 Palestine
  • 🇸🇦 Saudi Arabia, 🇦🇪 UAE, 🇶🇦 Qatar, 🇴🇲 Oman, 🇰🇼 Kuwait, 🇧🇭 Bahrain
  • 🇾🇪 Yemen, 🇲🇷 Mauritania, 🇸🇴 Somalia, 🇱🇾 Libya

Notable exceptions in the Arabic-speaking world: Morocco, Tunisia, and Algeria follow the French Last-Sunday-of-May convention because their calendar tradition reflects the colonial era’s lasting influence on civic dates rather than Egypt’s pan-Arab convention.

🇫🇷 The Last Sunday of May — France + Francophone Africa + Sweden

France’s Fête des mères was officially established in 1929 (and codified in law in 1950) on the last Sunday of May, with a fallback to the first Sunday of June if the last Sunday clashes with Pentecost. In 2026, Pentecost is on May 24, so the last Sunday of May (May 31) is clear — no shift needed.

The convention spread through France’s mid-20th-century colonial network and remained after independence in much of Francophone Africa: 🇸🇳 Senegal, 🇨🇮 Côte d’Ivoire, 🇲🇱 Mali, 🇹🇩 Chad, 🇨🇬 Republic of Congo, 🇨🇩 DR Congo, 🇨🇫 Central African Republic, 🇬🇦 Gabon, 🇨🇲 Cameroon, 🇲🇬 Madagascar, 🇲🇨 Monaco. The Maghreb adopted it as well — 🇲🇦 Morocco, 🇹🇳 Tunisia, 🇩🇿 Algeria — though their Arabic-speaking populations sometimes also mark March 21 informally. The 🇩🇴 Dominican Republic adopted the same date independently. Sweden’s Mors Dag also falls on the last Sunday of May, but for a different reason: the campaigner Cecilia Bååth-Holmberg picked the date in 1919 specifically because it landed AFTER Pentecost most years and gave families a non-religious occasion.

Note: not every Francophone African country uses Last Sunday of May. Burkina Faso, Niger, Benin, Togo, Comoros, and Djibouti use the 2nd Sunday of May convention — the date that arrived later via globalised media rather than colonial channels.

🇪🇸 The 1st Sunday of May — Iberia + Lusophone Africa + Three Eastern European Outliers

Spain set its Día de la Madre on the first Sunday of May in 1965 (it had previously been December 8, the Feast of the Immaculate Conception). Portugal’s Dia da Mãe matches. The convention propagated through Lusophone Africa — 🇦🇴 Angola, 🇲🇿 Mozambique, 🇸🇹 São Tomé and Príncipe, 🇬🇼 Guinea-Bissau, 🇹🇱 East Timor — and to 🇦🇩 Andorra by Spanish proximity. Three Eastern European countries also use this date for unrelated reasons: 🇭🇺 Hungary, 🇷🇴 Romania, and 🇱🇹 Lithuania.

🌺 March 8 — Where Mother’s Day Folds Into International Women’s Day

In a band of post-Soviet and former-Yugoslav countries, the Soviet-era practice of celebrating International Women’s Day (March 8) absorbed Mother’s Day functionally. There’s no separate Mother’s Day on the calendar — March 8 covers it culturally:

  • Central Asia: 🇰🇿 Kazakhstan, 🇺🇿 Uzbekistan, 🇰🇬 Kyrgyzstan, 🇹🇯 Tajikistan, 🇹🇲 Turkmenistan, 🇦🇿 Azerbaijan
  • Balkans: 🇧🇬 Bulgaria, 🇦🇱 Albania, 🇲🇪 Montenegro, 🇽🇰 Kosovo
  • Other: 🇲🇩 Moldova, 🇰🇭 Cambodia (de facto)

This isn’t a perfect match. International Women’s Day is broader — it commemorates working women, the suffrage movement, and gender-equality struggles, not maternal kinship specifically. But in conversational use across these countries, March 8 IS the day you give your mother flowers. Russia is the major exception in this cluster: it observes IWD on March 8 AND a separate Mother’s Day on the last Sunday of November (instituted 1998).

📅 The Unique Cases — Each Country’s Own Story

Roughly 30 countries observe Mother’s Day on a date that doesn’t fit any of the five rule clusters above. Each has its own historical reason.

CountryDateWhy
🇷🇺 RussiaLast Sunday of November (Nov 29 in 2026)Established by Yeltsin presidential decree in 1998, after IWD-as-mother’s-day proved insufficient

🇲🇽 MexicoMay 10 (fixed)Set by 1922 newspaper campaign on a fixed date; never floats to a Sunday — falls on a workday more often than not
🇧🇴 BoliviaMay 27 (fixed)Commemorates the 1812 Battle of La Coronilla, where women defended Cochabamba
🇦🇷 Argentina3rd Sunday of October (Oct 18 in 2026)Originally tied to October 11 (former feast of the Maternity of Mary); shifted to the 3rd Sunday after Vatican II
🇳🇮 NicaraguaMay 30 (fixed)Birthday of Casimira Sacasa, mother of dictator Anastasio Somoza García’s wife — set by Somoza in 1939
🇵🇾 ParaguayMay 15 (fixed)Independence Day — combined to honor “mother country” and biological mothers
🇸🇻 El SalvadorMay 10 (fixed)Same fixed-date convention as Mexico, adopted via cross-border culture in the 1940s
🇬🇹 GuatemalaMay 10 (fixed)Same as El Salvador — fixed-date Latin American adoption
🇨🇷 Costa RicaAugust 15 (fixed)Coincides with the Catholic Feast of the Assumption of Mary
🇵🇦 PanamaDecember 8 (fixed)Coincides with the Feast of the Immaculate Conception (originally Spain’s Mother’s Day too)
🇸🇮 SloveniaMarch 25 (fixed)Coincides with the Feast of the Annunciation
🇬🇪 GeorgiaMarch 3 (fixed)Established 1991 as a deliberate distinct-from-IWD national holiday
🇦🇲 ArmeniaApril 7“Day of Motherhood and Beauty” — coincides with the Annunciation in the Armenian Apostolic calendar
🇮🇩 IndonesiaDecember 22 (fixed)Hari Ibu — commemorates the first Indonesian Women’s Congress (Yogyakarta, 1928)
🇹🇭 ThailandAugust 12 (fixed)Birthday of Queen Sirikit (1932–2024); kept as Mother’s Day in her memory
🇻🇳 VietnamOctober 20 (de facto)Vietnamese Women’s Day — covers Mother’s Day in conversational use
🇳🇴 Norway2nd Sunday of February (Feb 8 in 2026)Set in 1919 by the Norwegian Sanitary Association; moved to February to fall after Christmas but before Easter
🇳🇵 NepalMata Tirtha Aunsi — April 17 in 2026Lunar calendar — falls on the new moon of the month of Baisakh (April–May); pilgrims visit Mata Tirtha temple west of Kathmandu
🇦🇫 AfghanistanJune 14Date set by Royal Decree in 1962, never followed Western convention
🇱🇺 Luxembourg2nd Sunday of June (Jun 14 in 2026)Established 1924 by Patriotic Mothers’ League — distinct from neighboring Germany/Belgium/France conventions
🇰🇷 South KoreaMay 8 (Parents’ Day, fixed)“Eobeoinal” — combined Mother’s + Father’s Day since 1973
🇰🇵 North KoreaNovember 16 (fixed)Established 2015 to commemorate Kim Il Sung’s 1961 speech on motherhood
🇲🇳 MongoliaJune 1 (fixed)“Mothers’ and Children’s Day” — combined holiday on International Children’s Day

Why So Many Different Dates?

Mother’s Day looks idiosyncratic country-by-country because there’s no single international body with authority over it (unlike, say, May 1 Labour Day, which the Second International standardised in 1889). The current map is a patchwork of:

  • American export (1914 → present): the 2nd-Sunday-of-May convention spread through US media, missionaries, and post-WWII cultural influence — the largest single cluster on the map
  • European national legislation (1919–1965): France, Spain, Sweden, Norway, Belgium, Luxembourg each picked a date independently in the early-to-mid 20th century, and the colonial successor states often inherited their choice
  • Religious feasts: Mothering Sunday (4th Sunday of Lent), Annunciation (March 25), Assumption (Aug 15), Immaculate Conception (Dec 8), Protection of the Mother of God (Oct 14) — these are pre-existing Catholic/Orthodox observances that became Mother’s Day in some countries
  • Soviet IWD overlap (post-1917): in much of the post-Soviet space and parts of the Balkans, March 8 IWD absorbed the maternal-celebration role
  • National-symbolic dates: Russia (Yeltsin 1998), Indonesia (1928 Women’s Congress), Thailand (Queen’s birthday), Bolivia (1812 battle), Nicaragua (Somoza 1939), Mexico (1922 newspaper campaign), Paraguay (Independence Day) — each tied to a specific local moment
  • Lunar / pre-modern calendars: Nepal’s Mata Tirtha Aunsi is the clearest example — a date that floats by lunar reckoning, predating the Gregorian Mother’s Day movement entirely

The clustering on the map reflects empire-by-empire propagation more than coordinated international convention. The British Empire mostly spread Mothering Sunday (later replaced by 2nd-Sunday-May in most successor states); the French Empire spread Last-Sunday-of-May; the Spanish Empire spread 1st-Sunday-of-May (sometimes May 10 fixed in Mexico’s case); the Soviet Empire spread March 8; the Arab League adopted March 21 within a decade of Egypt’s 1956 reform.

So When Is Your Mother’s Day?

If you’re in the global majority — the 110+ countries on the cream side of the map — the second Sunday of May is May 10 this year. Five days from today’s writing. If you’re in France or Sweden, you’ve got three more weeks. If you’re in Egypt or Saudi Arabia, you marked it back on March 21. If you’re in Russia, it’s still half a year away. If you’re in Indonesia or Thailand or Nepal, your date follows a logic that has nothing to do with anyone else’s. And if you’re in one of the post-Soviet republics where March 8 covers it, you celebrated mothers, daughters, sisters, and aunts all at once two months ago.

Wherever you are on the map: the day is whatever your country says it is. Don’t miss it.
