Canberra, Australia · UTC+11 ☆

Canberra is Australia’s purpose-built national capital, sitting in the Australian Capital Territory (ACT) between Sydney and Melbourne. It runs on Australia/Sydney: UTC+10 in winter (Australian Eastern Standard Time), UTC+11 in summer (Australian Eastern Daylight Time). The ACT observes DST, unlike neighboring Queensland.

Canberra was selected as the capital through a political compromise in 1908: neither Sydney (NSW) nor Melbourne (Victoria) would accept the other as the national capital, so a new city was designed in a sparsely populated inland valley between them. The capital’s location in New South Wales but governed as a separate territory means it follows NSW timezone rules, which include DST.

The designed capital

Walter Burley Griffin and Marion Mahony Griffin won the international design competition for Canberra in 1912. The city was built around a central lake (Lake Burley Griffin, created in 1964 by damming the Molonglo River) with government buildings on the southern shore and the commercial center on the north. The design is formal and geometric in a way that most cities, which grow organically, never achieve.

Canberra’s latitude of 35 degrees south gives it significant seasonal daylight variation: December sunsets after 8pm, June sunsets before 5:30pm. The government quarter, Parliament House, and the various national institutions have their own rhythms defined by parliamentary sitting periods rather than the sun.

Government time

When parliament is sitting, Canberra is a busy city. When it’s in recess, the city quiets noticeably. The parliamentary calendar structures the city’s economic and social rhythms in a way that has no parallel in other Australian cities. Public servants align their leave with parliamentary recesses.

The time conversion from Canberra to London puts London ten hours behind in winter. Sydney is on the same clock.
