On October 1, the best‑known “National Day” is China’s National Day , which marks the founding of the People’s Republic of China on October 1, 1949, and is celebrated across mainland China, Hong Kong, and Macau with ceremonies, parades, and fireworks.

Quick Scoop: What national day is Oct 1st?

Think of October 1 as a double‑layered date: a serious state holiday in China, and a fun cluster of themed “national days” in pop culture calendars.

1. The major one: China’s National Day

  • It’s the official National Day of the People’s Republic of China , celebrated every year on October 1.
  • It commemorates Mao Zedong’s proclamation of the PRC in Tiananmen Square on October 1, 1949.
  • Mainland China marks it with flag‑raising ceremonies, big public events, and in some years a grand military parade in Beijing.
  • Hong Kong and Macau also observe it as a public holiday with official ceremonies and harbour fireworks shows.

In modern terms, if you see big Golden Week travel rushes, red flags everywhere, and huge crowds in Beijing and Hong Kong around early October, that’s this day in action.

2. Other “national days” on October 1 (mainly U.S.-style observances)

Alongside the serious state holiday, October 1 has a whole menu of lighter “national days” commonly listed in U.S. and internet calendars.

Some examples include:

  • National Hair Day – a day celebrating hair care and styling, founded in 2017 by NuMe and National Day Calendar.
  • National Homemade Cookies Day – a popular food‑themed day for baking and sharing cookies.
  • International Coffee Day / World Coffee Day – widely used to celebrate coffee culture worldwide.
  • National Green City Day – promoting greener, more sustainable cities.
  • Other fun listings you may see: National Black Dog Day , National Poetry Day (in some calendars/regions), and various quirky observances.

These are not official government holidays; they’re more social‑media/marketing calendar style “national days” that websites compile.

3. Forum / trending angle

If people on forums ask “what national day is Oct 1st?” , they usually mean one of two things:

  1. The geopolitical answer:
    • “It’s China’s National Day, marking the founding of the PRC in 1949 and the start of Golden Week.”
  1. The fun calendar answer:
    • “Depending on which site you follow, it’s National Hair Day, Homemade Cookies Day, International Coffee Day, and more.”

Debates often pop up about whether these lighter “national day” lists are meaningful traditions or just marketing hooks, especially when stacked against a major state holiday like China’s National Day.

4. One‑line TL;DR

On October 1, the official, globally significant “National Day” is China’s National Day , while various pop‑culture calendars also label it with fun observances like National Hair Day , National Homemade Cookies Day , and International Coffee Day.
