I am well aware with some people's believing of transitioning into China's (Loyang's) time. You can believe that. ZiWei is the calculation (or interpretation) of the interaction with human with sun, moon and other astrso. US and China(Asia) is almost 180 degree apart(day and/or night). People born in Japan and born in HK have one hour difference in sun ray orientation, even though they are born at the SAME punctual time. That is why smart people come up with Time Zone. The 15-hr difference of Time Zone has also factored into the sun ray orientation.

If you are born and live at USA, even though you can find your Providencial birth time, it will not follow what you see on your chart, because of fenshui/geomantics. Your living environment and people you deal with have a big impact to your life trek(butterfly!). For example, my wife and her twin sister have an IDENTICAL life till after medical schools (doing Residence training together) and before weddings. After weddings, their life treks start to deviate year-by-year. At the beginning of weddings, I did notice some "providencial accommodation" in life trek,like miscarriage, long-term job travel. etc.

Whether your father is dead or alive, can not just by seeing the chart. Fortune Teller always have a lot of disclaiming excuses. Typically one is your parents' marriage has affair(s), illness, mother is older, second marriage, etc. I can list at least 10 that do not follow the chart.
My life track does not match with my chart, even two charts.

For leap month issue in lunar calendar, you can try BaZi which is solar based...

Fortune Telling became a entertainment (or halothanic) Business or Industry. ZiWei becomes self-fulfilling, especially in the subconscious mental status. Choose one time segment(chart) you like and believe it. It will come true, just like a book" The SECRET" by Rhonda Byrne.
