Introduction

There is always something interesting happening in the sky. The Moon cycles through its phases and occasionally passes near a bright planet or star. Sometimes the Moon eclipses the Sun. And sometimes the Moon is eclipsed as it passes through Earth's shadow. The planets move against the stars and are most prominent at opposition (Mars, Jupiter and Saturn) or at greatest elongation (Mercury and Venus). Earth makes its annual orbit around the Sun and passes through its four seasons.

SKYCAL (Sky Events Calendar) will help you keep track of the sky by calculating the local date and time of all these celestial happenings. It displays them on a convenient calendar that you can print and hang on the wall. You can generate a calendar for a single month or for an entire year. Just choose your Time Zone.

To use SKYCAL, make your selections in three simple steps:

  • Section 1: Select a Time Zone for the sky events you wish to generate.
  • Section 2: Select the either the year or the year and month of the sky events.
  • Section 3: Select either Calendar or Table format and then generate your custom sky events output.

Note that all generated times are for Standard Time in your chosen time zone. If your location uses Daylight Saving Time (DST) (called called Summer Time (ST) in Europe) for part of the year, you must add 1 hour to the generated Standard Time when Daylight Saving Time is in effect. The default Time Zone used by SKYCAL is based on the zone setting of your computer's internal clock.

Besides the traditional 7-day per week calendar format, you can also display the sky events in a table (opened in a new window). This format shows additional information about many events because it has more room to display the extra data. The table can be copied and saved/printed.
