Almanac® Pro online provides for each day of the year information on the different types of energy present that day.

Some of this information is raw (stems, branches, hexagrams, stars) and another is already a form of interpretation (sign forecasts or activities).

The window consists of 3 main areas: a header, a footer and the almanac itself.

The specificity of chinese-arts.app Almanac®  is to take into account the time zone where you are and to be able to specify another one.

Importance of timezone

Taking timezone into account is mandatory each time one tries to link an astronomical event and the calendar. Days always start a midnight local time, but month are related to solar segments or new moons, depending on the kind of frame one uses.

Theses astronomical events occur at the same moment for everyone on earth, thus at different local times. Only the days that are a solar segment or a new moon are concerned by this factor, but pour some people or situations, that can change things a lot. So it is important to consider it.

Stars based on solar segments or new moons can occur that day or the day before depending on where you are on earth. Month pillar can also be different. The impact on a date can be huge.

Default timezone

By default, Almanac® Pro will take the timezone of you computer or tablet. If you deal only with persons of the same country or timezone that you, this will be transparent to you. Take care to daylight saving time that can be different from one country to anonther, even if you share the same timezone. Almanac® Pro will deal with these 2 parameters.
Almanac® Pro gives for all dates the time shift of the event, be it a day or ephemeris.
For example in France, timezone is Europe/Berlin. On october 23, time shift is 2 heures relatively to universal time (UTC), formely called Greenwhich meridian (GMT). So the indicator is UTC+2. In this timezone, winter daylight saving time changes on october during the night. On the 26, the Almanach will flag UTC+1.
