# static getApparentLocalSiderealTime(jd, lng) → {Hour}
The apparent local mean sidereal time (sun's clock time) for a given julian day, corrected for the
nutation, at a given longitude on Earth
Parameters:
# static getDate(jd) → {Date}
Computes the date corresponding to the Julian Day
Parameters:
| Name | Type | Description |
|---|---|---|
jd |
JulianDay
|
The julian day |
Date
# static getJulianCentury(jd) → {JulianCentury}
The Julian Century (time interval of 36525 days)
Parameters:
| Name | Type | Description |

# static getJulianDayMidnight(jd) → {JulianDay}
The Julian Day of Midnight UTC for a given Julian Day.
Parameters:
| Name | Type | Description |

The initial julian day |
# static getJulianDayMidnightDynamicalTime(jd) → {JulianDay}
The Julian Day of Midnight Dynamical Time (not exactly equal to UTC) for a given Julian Day.
When computing rise, transit and set times, the input equatorial coordinates must be first
computed at these times.

# static getJulianMillenium(jd) → {JulianMillenium}
The Julian Millenium (time interval of 365250 days)
Parameters:
| Name | Type | Description |
|---|---|---|
jd |
JulianDay
|
The initial julian day |
# static getLocalSiderealTime(jd, lng) → {Hour}
The local mean sidereal time (sun's clock time) for a given julian day
at a given longitude on Earth
