Maxclock iconMaxclock 3.3

An astronomical clock that can display civil date, julian date and mean solar time
Essentially, MAXCLOCK is a high-precision digital astronomical clock. Time information is displayed for ITRF Greenwich zero meridian. Sidereal and solar times will be also displayed for any other freely user-selectable geographical location anywhere on planet earth, such as your home observation site.

Display is on the screen of your computer and is continuously updated as the computer clock runs, the update interval can be selected between one and 60 seconds (fully-automated clock mode).

Acoustic signalling (time beeps) can be selected and update can also be initiated manually (semi-automated clock mode). To do this, MAXCLOCK only uses the internal clock of the computer and an easy-to-edit configuration file.

Computations may also be made for user-supplied date & time (typed through keyboard or read from file, non-clock mode), and output may also be directed to a protocol file.

Main features:

  • Civil date & time, day number in the year
  • Julian date and modified Julian date both in terms of
  • ephemeris time ET (TT) and universal time UT1
  • Delta-T, the difference between ET and UT1
  • Mean solar time, apparent solar time, equation of time
  • Mean sidereal time, apparent sidereal time
  • equation of equinoxes
  • Geocentric ecliptical and equatorial coordinates of sun and
  • moon (with/without nutation and aberration selectable
  • referenced to mean dynamic equinox and ecliptic of date or to
  • FK5)
  • Constellation and zodiac sign for the sun
  • Constellation, zodiac sign, phase, appearance, and illuminated
  • fraction of the moon
  • Elongation between sun and moon
  • Earth distance to sun and moon
  • Announcements for equinoxes, solstices, and moon phases
