The saguaro grows only in the Sonoran Desert around Tucson, reaches about 12 metres and can live 150 to 200 years — but does not grow its first arm until somewhere around age 70. Two national park units protect them either side of the city.
The clock: Arizona does not observe daylight saving, so Tucson matches Los Angeles in summer and Denver in winter without moving its own clocks.
Tucson lies at 111.0°W. Its time zone, UTC−7, is built around the 105°W meridian. The 6.0° gap between them means the clock runs roughly 24 minutes ahead of the sun: solar noon arrives at about 12:24 rather than 12:00. The zone holds UTC−7 all year — there is no daylight saving here.
The longest day of 2026 is 22 June, with 14h 16m of daylight. The shortest is 22 December, with 10h 2m. The swing between them is 4h 14m. At this latitude the seasons are visible in the clock, but never dramatic.
The earliest sunrise and the latest sunset do not land on the longest day. In Tucson the sun comes up earliest on 13 June at 05:16, while the latest sunset waits until 1 July at 19:34. The equation of time is what separates them: the Earth's elliptical orbit and axial tilt move solar noon back and forth by several minutes over the year.
The sky stays usably light for a while after the sun goes down. In Tucson that civil twilight runs about 24 minutes at the equinox.
