Jul 05, 2017 People associate the iCalendar format with Apple products, but it’s actually an open standard, and Google Calendar supports it. This means that both iCalendar downloads and iCalendar URLs work well with Google’s online calendar, though the way to add them is somewhat hidden. Try the Chinese Lunar Calendar by add this ics file to your favorite calendar app. Start and end date can also be specified as command line options, for example./lunarical.py -start=1990-01-01 -end=2001-01-01 The date must in ISO format. There is also a C version under directory 'c'. Run make to generate the executable lunarcal. ICalendar's calendar is also not compatible with some non-Gregorian calendars such as the lunar calendars used in Israel and Saudi Arabia. The memo 'Calendar Access Protocol' (RFC 4324) was an initial attempt at a universal system to create real-time calendars. This protocol was eventually abandoned, possibly because of excessive complexity. The Moon phase calculator shows exact times of the various moon phases for Vancouver, British Columbia, Canada in year 2020 or in other locations and years.

Calendar is self-hosted
Subscribing to this calendar will insert dates and times of astronomical significance including full moons, new moons, eclipses, equinoxes, solstices, plus a meteor shower or two and other surprises worth noting into your iCal-compatible software / iPhone / cybernetic mutant brain chip.
2-3 items per month. Self-updates at the beginning of each year. Some calendar items include notes, for example URLs where you can figure out if you're in the path of a particular eclipse.

Introduction
There is always something interesting happening in the sky. The Moon cycles through its phases and occasionally passes near a bright planet. Sometimes the Moon eclipses the Sun. And sometimes the Moon itself 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 calendar you wish to generate.
- Section 2: Select the sky events to include in the calendar (moon phases, eclipses, planet positions, meteor showers, etc).
- Section 3: Select the year or year and month of the calendar.
For time zones in North America and Europe, a Daylight Saving Time (DST) control appears that can be toggled on or off.In most of North America, DST is observed from the second Sunday of March through the first Sunday of November. In Europe, DST is called Summer Time (ST). ST is observed from the last Sunday of March through the last Sunday of October. The initial settings of SKYCAL (Time Zone & DST) are based on the time zone setting in your computer's internal clock.

All sky events in section 2 are selected by default. Change them as needed. In Section 3, enter the year or year and month of your calendar. At present, SKYCAL works for all years from 1801 through 2100. This range will increase soon. You can select calendars other than the western Gregorian Calendar by clicking the Other Calendars button and choosing a calendar from the drop-down menu.
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 printed and saved.
