# How do you calculate solar day sidereal day?

Solution: 360o/day + 360o/(365.2422 days) (360/360.9856) x 24 hours = 23.9345 hours. (24 hr/solar day)/(23.9345 hr/sidereal day) = 1.0027 sidereal day/solar day. (365.2422 solar days) x 1.0027 = 366.2284 sidereal days. (0.683 sidereal days) x (23.9345 hr/sidereal day) = 16.347 hr.

Why are the solar and sidereal day different lengths?

New crust is being pushed away from the sea-floor spreading boundaries. The Earth is not getting any bigger.

### One may also ask how do you convert to sidereal time?

AST = HAsun + 12h AST range = 0h to 24h . Sidereal Time is measured by the position of the Vernal Equinox with respect to the celestial meridian. One Sidereal Day is the interval between successive transits of the meridian by the Vernal Equinox. One Sidereal Day = 23h 56m 04s. Why are the solar and sidereal day different lengths? The difference between the sidereal and solar day is due to the orbital motion of the planet. For the planets with their orbital motion in the same direction as their rotation (Mercury, Earth, Mars, Jupiter, Saturn, and Neptune), the solar day is longer than the sidereal day.

### Also, what is my local sidereal time?

Calculating Your Local Sidereal Time (LST) Given the local longitude, date and time. Convert the date and time to UTC. Calculate Greenwich mean sidereal time (GMST). Using the local longitude, shift GMST to LST. Display LST in hours, minutes, and seconds. Subsequently, what is local mean sidereal time? LMST - Local Mean Sidereal Time Local Mean Sidereal time is GMST plus the observer's longitude measured positive to the east of Greenwich. This is the time commonly displayed on an observatory's sidereal clock. LMST = GMST + (observer's east longitude)

How long is a sidereal day?

Before the great and terrible day of the Lord, the sun will be turned into darkness and the moon into blood. The time is 2:31. Before the great and notable day of the Lord, the sun will be turned into darkness and the moon into blood. Acts 2:14.

### Moreover, is sidereal time more accurate?

There is no difference between 1 second of sidereal time and 1 second of mean solar time. There's currently about a 236 second difference between 1 sidereal day and 1 mean solar day. A sidereal day is the amount of time that it takes for the Earth to complete 360 degrees of spin rotation.
