Southern-Hemisphere Prayer Times
Sydney's seasons run opposite to most of the world's Muslim-majority countries. That flips the yearly pattern of prayer times too. Understanding that inversion helps explain why Sydney's calendar can look unfamiliar next to a calendar built around a northern-hemisphere city.

The pattern, reversed
Sydney's solstices run the opposite way
December solstice
Sydney's longest days: earliest Fajr, latest Isha. The opposite of a June/July peak in the northern hemisphere.
June solstice
Sydney's shortest days: latest Fajr, earliest Maghrib. The opposite of a northern-hemisphere winter low.
What this means for Ramadan
Because fasting runs from Fajr to Maghrib, a Ramadan that falls in Sydney's summer months means longer fasting days than a Ramadan falling in winter. The direction of that swing runs opposite to what someone in the northern hemisphere would expect for the same calendar month.
See Ramadan in Sydney for this year's specific dates and fasting-hour figures.

Frequently Asked Questions
Are Sydney's longest prayer days in summer or winter? +
Summer, which in Sydney falls in December and January. Fajr is earliest and Maghrib latest around the December solstice, giving the longest stretch between Fajr and Isha of the year.
Why do some apps or calendars look wrong for Sydney? +
Software written and tested against a northern-hemisphere city can carry assumptions about which months have the longest days baked into its interface or defaults. Sydney's actual calculated times are correct either way. The underlying astronomy accounts for the southern hemisphere automatically.
Does Ramadan's daily fasting length change with the seasons in Sydney? +
Yes. Since fasting hours run from Fajr to Maghrib, a Ramadan that falls during Sydney's summer months means longer fasting days, while one falling during winter means shorter ones. It's the same effect northern-hemisphere countries see in reverse.
