Astronomical Sunrise 05:45 AMAstronomical sunrise occurs when the Sun is 18° below the horizon and the sky begins to brighten from a completly darkened state.
Nautical Sunrise 06:16 AMNautical sunrise (or nautical dawn) is the precise moment when the sun's center is 12° below the horizon in the morning. It marks the beginning of nautical twilight, allowing pilots/mariners to see the horizon.
Civil Sunrise 06:47 AMCivil sunrise is the moment in the morning when the sun's center is 6° below the horizon. It marks the start of morning civil twilight, providing enough natural light for most, outdoor activities without artificial lighting. It typically occurs roughly 20-30 minutes before actual sunrise.
Sunrise 07:13 AMSunrise (or sunup) is the moment when the upper rim of the Sun appears on the horizon in the morning. It marks the end of the twilight phase, often accompanied by distinct atmospheric colors.
Daylight: 11 Hours 27 MinutesDaylight hours are the period of time between local sunrise and sunset, representing the daily portion of sunlight. These hours change in length based on season, Earth's tilt, and latitude.
Sunset 6:40 PMThe sunset is defined in astronomy as the moment the upper limb of the Sun disappears below the horizon. It marks the end of daylight and is often accompanied by distinct atmospheric colors. It also signals the beginning of twilight.
Civil Sunset 7:07 PMCivil sunset (or evening civil twilight) occurs when the center of the sun is 6° below the horizon, marking the end of the brightest twilight phase. It typically occurs roughly 20-30 minutes after sunset, providing enough light for most outdoor activities to continue without artificial light.
Nautical Sunset 7:38 PMNautical sunset occurs when the sun's center is 12° below the horizon, marking the end of nautical twilight.
