The KhaldeaCalendar 2020 is an exquisite fusion of art, symbolism and digital technology. Each month of KhaldeaCalendar features a astrological ephemeris of the highest precision and a calendar grid incorporating precisely timed astrological aspects and other astro-data, together with a striking abstract image and an inspiring motif for the month's zodiacal sign. The unique sequence of daily lunar phases which unfolds across the calendar face makes it easy to follow the Lunation Cycle from day-to-day and to place Lunation Planning into fruitful practice.

The KhaldeaCalendar makes it easy to benefit from Lunation Planning — a natural, organic time-management system based on the 29.5-day Lunation Cycle, the ever-changing cyclic relationship between the Sun and the Moon. Everyone, in their own way, naturally feels and performs better when they are attuned with its rhythm. When guided by this natural cycle, our projects and endeavors — be they long-term or short-term, acted out by an individual or by a group — are more successful and rewarding. Lunation Planning is the world's oldest time-management tool. Lunation Planning is universal, it is deeply rooted in all cultures and religions. It is the foundation of virtually all ancient calendars, including the Hebrew, Islamic and the Chinese calendars.

Lunation Planning isn't going to save the world. We have to change our attitudes ourselves, but Lunation Planning can help us attune ourselves to a more relaxed, natural and harmonious pulse of living, which in turn may lead to a gradual change of attitude toward ourselves and toward the world.

Lunation Planning is available a Amazon Worldwide. US readers, find Lunation Planning and other Khaldea Publications at

4. What's New

Year 2016 brings version 2 of the KhaldeaCalendar. Some of the new features and enhancements found in version 2 are outlined above, and they are summarized below.

User Enhancements
The calendar grid features improved graphics and an extended astrological data section. See the "Symbols" section for a key to the astrological symbols and colors used. Previous users will notice some important changes to the colors used on the calendar grid. Waning aspects are now indicated by blue glyphs, replacing dark red. Retrograde planets in aspect are now shown in red. Solar ingress are no longer highlighted.

Version 2 is faster and easier to use. Months of the year are now navigated via interactive tabs, and the entire year is wrapped in a single web page. It's also easier for online users to change time zone — just use the dropdown list beneath the calendar grid to jump to any of 14 time zones worldwide. And this year Hawaii and Nepal have been added to the list.

The digital Khaldea Astrological Calendar has been repackaged for version 2 — it now includes art, verse and an ephemeris upgrade. Use the new control panel described above to easily access it all. Just click on a icon to expand or contract an "accordion panel." It's easier to use than to read about. As a special bonus, version 2 features daily geocentric longitudes, latitudes and declinations from the KhaldeaEphemeris7z.

KhaldeaCalendar version 2 is produced by KhadeaTechnology's scalable vector graphics engine that creates astrological images in several vector and raster formats, including .pdf, .svg, .wmp,. tiff, .png, .jpg, and .gif. The digital Khaldea Astrological Calendar uses .png raster images.

The KhaldeaCalendar module of KhaldeaTechnology is "theme-based" and Unicode compliant — making it's output highly customizable. It can use any aspect set (within constrains of space), or show no aspects; show phases, or no phases; any holiday or event can be displayed. Language modules and unicode enables any language, any script. For print work, press-ready pdf files for entire calendars can produced, as seen in this example.
