Frequently asked questions

Swiss Ephemeris > Printable Ephemeris

  1. What is the difference between GMT and UT?

    There is no difference between GMT (Greenwich Mean Time) and UT (Universal Time), GMT is just an older name.

  2. What does Delta T = [number] mean?

    Delta T indicates the difference between UT and TDT (Terrestrial Dynamic Time), which used to be called 'Ephemeris time' in the last century. While UT is not a uniform time scale (it is occasionally adjusted, due to irregularities in the Earth's rotation), TDT is a uniform time scale which is needed as an argument for mathematical theories of celestial movements.

  3. Do you offer a printable sidereal ephemeris?

    Yes, we have. You can create one for any time period you like.

    Please go to extended chart selection, ephemeris.

  4. Trying to access one of the ephemerides for new planets / asteroids, the page gets stuck. Why is that?

    This is most likely a bug in the Internet Explorer. It displays long text data tables very slowly. You may have to wait up to 3 minutes for the page to display, and it finally will.
