Cute lunar calendar with some miscalculations

It's my first lunar calendar app - the structure is simple - the service also. In addition, certain areas can be selected, which are then transferred to a planner or in a ext. Calendar eg google.Konto (if any) can be transferred. It's all clear - only has the app a serious quirks: The assignment for each zodiac sign is only "lapidary" captured: Ex. 18 August 2014 - here indicated in characters lions - in 90% of all paper calendar it is day as twins expected - why? Because the moon on the day to 0:41 changes into Gemini (although it starts in Leo) and thus more than 23 hours of the day are twin hours. Today at 26.7. (. 17 hours in cancer) - New Moon in Cancer - I'm confused: If you specify the back cutting fruit trees even as "good".
If you read it in various books that indeed less of the new moon -. However, the moon in the sign of Cancer is quite unfavorable for fruit Topiaries. Furthermore, August 11 is given as "very good" for cleaning windows - at 10:08. Aquarius also decreasing (24 hours long - so ideal) there is nowhere to be found.
All in all, nicely modeled easy to handlen for those interested as gross entry / guide - by the inconsistencies I leave with but not 100% on the App ...
