Local horizon obstructions (mountains, tall buildings) can shift the visible sunrise/sunset by a few minutes compared to the calculated value.
How long is the longest day of the year in Simi Valley?
At Simi Valley's latitude of 34.27° N, the longest day stretches to about 14h 18m on the June solstice. The shortest day, on the December solstice, is around 9h 42m — a year-round swing of roughly 4h 36m.
When is golden hour in Simi Valley?
Golden hour in Simi Valley occurs in the ~60-minute window after sunrise and before sunset, when the sun is low (typically below 6° elevation) and light is softer and warmer. Photographers favour this window for portraits and landscapes. The exact start/end depends on the season — golden hour is shorter near the equinoxes and longer in winter when the sun travels at a shallower angle.
Do Simi Valley sunrise times change with daylight saving time?
Yes. All times shown here use Simi Valley's local clock, which switches between standard time and daylight saving time on the dates set by US federal law (second Sunday in March, first Sunday in November). The actual position of the sun does not change — only the clock face does. See our Daylight Saving Time guide for the next change date.
In which direction does the sun rise and set in Simi Valley?
In Simi Valley, the sun rises in the east, swinging northeast in summer and southeast in winter, and sets in the west, swinging northwest in summer and southwest in winter. On the equinoxes (around 20 March and 22 September), the sun rises due east and sets due west. Between those dates, the sunrise/sunset points shift along the horizon as Earth's axial tilt changes the sun's declination.
What is solar noon, and when does it happen in Simi Valley?
Solar noon is the moment the sun is at its highest point in the sky for the day. In Simi Valley, solar noon arrives roughly right at clock noon, because Simi Valley sits in the central partof its time zone. The exact offset shifts a few minutes through the year due to Earth's elliptical orbit (the "equation of time").
