Mars and more.

Input a four digit year and a numerical month and day to see the planetary signs/degrees for that day. The program will also display below it the position of the planets now. If you supply a geographic location via coordinates (link to www.astro.com's atlas page below), houses for the time you entered and now will be shown. For those unfamiliar with houses, the twelfth houses starts just after sunrise, at that location, and the houses progress through the day back to the 1st house which ends just before sunrise.

If you enter a time it should be UTC time. Use an hour from 0-23. More notes on how to convert to UTC time below. You can always just click submit, and you will see two charts of planets now, with the current UTC time printed above each chart. Bear in mind if it's daylights saving time, and the time you want didn't occur during daylights saving time, UTC does not observe daylights savings time.

If you leave the field blank, the current value of that field will be used. I.E. if you leave hour and minute blank, it will use the current hour and minute converted to UTC time.

Below is only necessary for house positions. The longitude and latitude should be the location of your birth, or the place you want the houses for, if now.

To look up the longitude and latitude of a city in the world, see: Search cities

If you don't have an exact birth time or close, then house positions won't be accurate. The start of your houses depends on both the time and the location, and is based on the sun's position, in terms of sunset and sunrise, at your birth.

The international time standard (formerly Greenwich Mean Time, or GMT) is UTC. Zero hours UTC is midnight in Greenwich, England, which is located at 0 degrees longitude. Everything east of Greenwich (up to 180 degrees) is later in time, everything west is earlier.

Examples:

  • 7 AM in Pacific time in the winter is 15 UTC. 7 AM Pacific, in the summer, is only 14 UTC because the clocks went ahead for daylight savings time in the Pacific time zone, but did not for UTC.

  • 11 PM or 23 Pacific time on the 28th of December in the winter is 7 UTC on the 29th.

  • In the summer 11 PM or 23 Pacific time is + 7 or 6 AM or 6 UTC.

  • East Coast USA is time + 5 to get to UTC in winter and time + 4 in summer. Pacific time is +8 in the winter and +7 in the summer.
