swetest is the Swiss Ephemeris Test Page at astro.com (Astrodienst). learned how to use it reading 3 LILITHS INFO rev. June 17, 2003 by kumuastrosue.
astro.com also has a list of the numbered planets. simple steps to use this great feature:
 first, convert your time zone to UT. a quick+dirty way to do this is at Yahoo:
enter your city state (or province) and the words time zone. eg, nashville tn time zone. current time zone of nashville should appear. copy that. enter: london england time zone. copy that and compare. if you're in the US you're behind london; nashville is six hours (- 6:0 hours) behind london (or, GMT or UTC or UT):
Time in London, United Kingdom (GMT): 7:31 AM, Tuesday, Jan 25, 2005
Greenwich Mean Time (GMT) is Coordinated Universal Time (UTC) + 0:0 hours
Time in Nashville, TN, USA (CST): 1:31 AM, Tuesday, Jan 25, 2005
Central Standard Time (CST) is Coordinated Universal Time (UTC) - 6:0 hours
