Remember!  You have to convert to China's time zone (Beijing time).  If you live in Chicago, at 10 am of May 24th, China is already the beginning of May 25th.  So if you threw the coins after 10 am of May 24th, you must record it as the 25th of May.  If you don't convert to China's time zone, your prediction will not be accurate. Just goto Google and type in Beijing Time, and you will see what time it is in Beijing.

I no longer update a Chinese calendar.  But you can use this free Super IChing hexagram creator to get today's Chinese calendar's sign and date.
