Sunrise time in Irvine

The sun rises in Irvine at 6:04 AM today and at 6:04 AM tomorrow (the same time as today).

Irvine daylight month by month

Sunrise, sunset, and total daylight for the first of each month in 2026, computed from Irvine’s coordinates in local time. The line traces how the day stretches toward summer and contracts toward winter.

Irvine’s longest and shortest days

Irvine’s longest day falls on June 21, 2026 with 14h 23m of daylight; the shortest is December 21, 2026 with just 9h 55m. The two equinoxes, when day and night run nearly equal, sit in between.

How fast Irvine gains and loses daylight

The pace of change is not steady. Each month gains or loses a different amount, fastest around the equinoxes and nearly frozen at the solstices. The rate below is the daily change mid-month; the net is the full swing across the month.

Irvine golden hour & blue hour by season

Golden hour is the warm, low-sun light; blue hour is the cooler twilight that brackets it. These windows come from Irvine’s true solar geometry — the sun’s altitude, not a fixed hour — so they stretch toward the solstices and run longer than the rule-of-thumb hour.

Daylight saving time in Irvine

Irvine springs its clocks forward on Sunday, March 8, 2026 and falls back on Sunday, November 1, 2026. Between those dates the local clock runs an hour later, so sunrise and sunset both read later — though the amount of daylight is unchanged; only the label on the clock moves.

Why sunset time shifts in Irvine

Sunset drifts through the year with Earth’s ~23.4° axial tilt — see the full daylight explainer.

In Irvine, the longest day carries about 14h 23m of daylight and the shortest just 9h 55m — a swing of roughly 4h 29m between the June and December solstices. The farther a place sits from the equator, the wider that gap; the pace also isn’t steady, moving fastest near the equinoxes and barely at all near the solstices. Every figure here is computed from the sun’s position for Irvine’s exact coordinates, in local time.
