Daily Ephemeris

Fill in the details below and click on "Calculate" to see Rise and Set times for the Sun, Moon and brighter planets. You will also see the dates and times for the New and Full Moon for the month you select. Default values for Latitude and Longitude are for Mount Stromlo Observatory.

Enter the date you want times for:	(dd/mm/yyyy) e.g. 20/9/2001 (This page is Y2K compliant!)
Enter your latitude:	(dd:mm:ss) negative for South of the equator
Enter your longitude:	(dd:mm:ss) negative for East of Greenwich
Enter your time zone:	(hh:mm) negative if you are behind UT (see below)

The "time zone" field is where you will need to enter the number of hours difference between your time zone and UT (or GMT). The default value shown is the correct value for Australian Eastern Standard Time where we are 10 hours ahead of UT. You will also need to allow for any daylight saving correction which may be current in your time zone. If you are unsure of the value to use here, visit The World Clock, click on a major city in your time zone and look for the value labelled "UTC/GMT Offset" - this is the number you want to put in the form above.

If you get garbage returned, check that you have entered the values in the fields correctly - especially four digits for the year. If you still get garbage, me the values you tried so I can track down the bug.

The code which does all the work for this page is a modified version of ephem, written by Elwood Downey (visit his xephem page for more information. Note that you will not find any information on Elwood's pages about this Web-ified version).
