Australia's longest day of the year is the Summer Solstice, which occurs annually between December 21st and 23rd, with the exact date varying slightly by year and time zone, making the day around December 22nd for most Australians, bringing the most daylight hours as the Southern Hemisphere tilts most towards the sun.
The summer solstice occurs annually across the Southern Hemisphere between December 21 and 23. In 2025, Australia's longest day falls on Sunday, December 21. From then on, our days will gradually become shorter than our nights until the winter solstice in Australia on Sunday, June 21, 2026.
21 June marks the longest day of the year, otherwise known as the summer solstice and according to the astronomical definition, the first official day of summer.
December 22nd is often associated with the longest day, but it's actually the Summer Solstice in the Southern Hemisphere, marking the most daylight hours and the start of summer there, while for the Northern Hemisphere, it's near the Winter Solstice (shortest day), occurring around December 20-23, depending on the year. This phenomenon happens because of Earth's axial tilt, with the Southern Hemisphere tilted most toward the Sun on this date, giving places like Australia its longest daylight, as noted in this article from Weatherzone and this Facebook post from the Powerhouse Museum.
June 20th is most significantly known as World Refugee Day, a United Nations observance honoring refugees' strength and raising awareness about their plight, established in 2001 to mark the 50th anniversary of the Refugee Convention. It also marks historical events like the Jaws movie release (1975), Nicole Kidman's birth (1967), and World Productivity Day, promoting efficiency and good work habits.
The summer solstice occurs in June in the Northern Hemisphere and marks midsummer: the 'longest day' and 'shortest night' of the year. On this day, the number of hours of daylight are at their maximum, while the number of hours of night are at their minimum.
Svalbard. Halfway between mainland Norway and the North Pole, you'll find the Svalbard Islands where the polar bears reside. Here, you can really talk about an endless day – the sun patrols the sky in almost uniform circles all summer.
The shortest day of the year in the Northern Hemisphere for 2025 was Sunday, December 21, marking the winter solstice (also known as the winter solstice) when the sun reaches its lowest point in the sky, resulting in the fewest hours of daylight, with the event occurring at 15:03 UTC. Conversely, for the Southern Hemisphere, December 21st was the longest day (summer solstice), while Australia's shortest day in 2025 was June 21st.
December 21st is known as the Winter Solstice, marking the shortest day and longest night of the year in the Northern Hemisphere (and the longest day/shortest night in the Southern Hemisphere) because Earth's axial tilt points that hemisphere farthest from the Sun, causing the Sun to appear lowest in the sky, starting ...
Midwinter is the middle of the winter. The term is attested in the early Germanic calendars where it was a period or a day which may have been determined by a lunisolar calendar before it was adapted into the Gregorian calendar.
2025 is shaping up to be among the warmest years on record, behind 2024 but rivaling 2023. Globally, northern hemisphere summer temperature records are being broken in some big and shocking ways, from the Arctic to Oceania, and in many places in between.
The next summer solstice for the Northern Hemisphere occurs on June 21, 2026, at 4:24 a.m. EDT (0824 GMT), and the summer solstice for the Southern Hemisphere occurs on Dec. 21, 2025, at 10:03 a.m. EST (1503 GMT). The summer solstice marks the official start of astronomical summer and the longest day of the year.
The winter solstice occurs during the hemisphere's winter. In the Northern Hemisphere, this is the December solstice (December 21 or 22) and in the Southern Hemisphere, this is the June solstice (June 20 or 21).
During the Northern Hemisphere's summer solstice, the upper half of the earth is tilted toward the sun, creating the longest day and shortest night of the year. This solstice falls between June 20 and 22.
April to May
Temperatures are still pleasantly warm in the south, whilst in the north the days are markedly drier and remote outback roads begin to open up. Autumn colours explode across south New South Wales, Victoria and Adelaide, and it is arguably the best time to visit the Australian outback.
So that's why Australia is a day ahead of America. Not the rest of the world though. Australia is on the same day as Japan for example, as well as the rest of East and South-East Asia. Note that there wasn't always an International Date Line.

The correct answer is 22nd December. The shortest day and the longest night of the year in the northern hemisphere occur during the winter solstice. Winter Solstice usually comes on 22nd December or 21st December. This is also the day of the longest day and the shortest night in the Southern hemisphere.
December 13 is the 347th day of the year (348th in leap years) in the Gregorian calendar; 18 days remain until the end of the year.
Most years have 52 weeks, but if the year starts on a Thursday or is a leap year that starts on a Wednesday, that particular year will have 53 numbered weeks.
For about three days around the solstice—December 19, 20, and 21—the Sun rises and sets at nearly the same spot on the horizon each morning and evening. To ancient observers without precision instruments, it looked like the Sun had stopped moving.
Christmas 2026: Friday, December 25.
Perfect for sunseekers, India has an average of 300 sunny days a year. It's a great winter destination, with peak season lasting from November to March.
The sun still rises and lightens Iceland for a short period every day. At its peak, December and January only experience 4-5 hours of daylight each day during winter.
Svalbard, Norway (Polar Night)
Svalbard is famous for attracting visitors during the polar night season of mid-November to the end of January. Then, the island is plunged into a seemingly everlasting night. This is your best chance to see the mystical aurora borealis, aka the Northern Lights.
