If you look up into the sky on a clear dark night, far from the intrusive glow of street lights, you'll see a faint band of starlight running across the heavens - The Milky Way. It's actually the disk of our own galaxy - seen from our own perspective. But what if we leave our Solar System and the Galaxy on a fantastic space ship and look back to our Space Island? What would we see? This screensaver simulates exactly this fantastic space scene as close to reality as possible using modern 3D technologies. You can download a free evaluation copy of our "Galaxy 3D Space Tour" screensaver or purchase an unlimited version. We tried to simulate this fascinating space view of the Galaxy using the latest astronomical knowledge. Color palettes, stars distribution within spiral galactic structure, dark and glowing nebulae, position and appearance of Magellanic Clouds (two tiny galaxies, satellites of our Milky Way) - every detail is carefully adjusted to match its actual appearance.

Millennia Calendar displays date and time for any locations on the Earth; includes 12 traditional and modern calendars (Julian, Byzantine, Gregorian, Indian, Ancient Egyptian, Coptic, Ethiopian, Hebrew, Islamic, Khayam, Persian, Slavic-Aryan); spans over a period of 7 thousand years (4 thousand years into the past and 3 thousand years into the future); takes into account the fact that in some calendars (Hebrew, Islamic etc.) new date begins either at sunset or sunrise; displays holidays and memorial days of many countries and religions: Christianity (Orthodoxy and Catholicism), Judaism, Islam (Shia and Sunni) and Ingleaism; allows historical and astronomical years counting; displays time of rise, transit and set of the Sun, the Moon and Planets; displays dates of equinoxes and solstices; displays dates and types of solar and lunar eclipses; displays horizontal coordinates of the Sun, the Moon and Planets; allows to save calendar and the list of holidays to HTML document; allows to saves the list of astronomical events to HTML or CSV document. Most of the astronomical calculations use algorithms set forth in the book 'Astronomical Algorithms' by Jean Meeus. Accuracy of these calculations is sufficient for the demonstration of correlation of astronomic events and calendars.

This utility can convert a gregorian date into julian day format/Modified Julian Day format and vice versa. The Julian Day Format counts the day since the 24th november -4713bc. The julian day format is often used in the astronomical section to calculate for example rises. This utility offers a fast and easyway to convert a gregorian date information to a julian day format or modified julian day format. The Modified Julian Day (MJD), introduced by the Smithsonian Astrophysical Observatory in 1957 to record the orbit of Sputnik, is defined in terms of the Julian day. It count the days since the 17th november 1858. It defines from the JD value as follow MJD =JD-2400000

The Chinese Lunar Calendar is a solilunar calendar, consisting of months corresponding exactly to lunar cycles and years which stay more-or-less in sync with seasonal years. The structure of the calendar depends on the exact times of certain astronomical events, principally dark moons and winter solstices.

The solar calendar consists of a series of seasonal years which are divided into 24 "solar terms". The lunar calendar consists of a series of years which are divided into 12 or 13 lunar months. A solar year always begins at the (northern) winter solstice. A lunar month always begins on the day of a dark moon.

Chinese Calendrics is used to do the following:

To convert between dates in the Chinese solar and lunar calendars and dates in the Common Era and Julian calendars.
To calculate the date of New Year's Day in the Chinese lunar calendar.
To ascertain the Western dates of the starts of all lunar months in a year in the lunar calendar.
To find leap months in the lunar calendar.
To find the Western dates corresponding to Chinese anniversaries (e.g., birthdays).
To move forward or backward from a given date (and time) either by a period such as a month (Western or Chinese) or by any number of days.
To calculate the phase of the Moon for any time within a 6000-year period.
To search for the next or previous full moon, dark moon, lunar quarter, solar term or solstice or equinox of a certain type.
To search for a solstice or an equinox in combination with a dark moon or a full moon.
To search for the next or previous day, month or year with a certain element-animal correspondence (e.g., the next water-rabbit year or the next fire-chicken day).
To find days for which the element-animal is the same for day, month and year.
