Sun, Earth and Moon   Moon Phases - Chinese Moon Festival Day

The date/time of moon age and the next four major lunar phases are in Universal Time (Greenwich Time, longitude=0).  To convert date/time of lunar phases to your local time zone is to add the date/time with your time zone hour number. For example,

New moon date/time is 09-03-05 18:45 at UT.

If PST (time zone = - 8), the new moon date/time is 09-03-05 10:45, after subtracting 8 hours
If EST (time zone = - 5), the new moon date/time is 09-03-05 13:45, after subtracting 5 hours.
If China (time zone = 8), the new moon date/time is 09-04-05 02:45, after adding 8 hours.

 

Daylight saving Time need to be adjusted for one hour
If PDT (time zone = - 8) , the new moon date/time is 09-03-05 11:45, after subtracting 7 hours
If EDT (time zone = - 5) , the new moon date/time is 09-03-05 14:45, after subtracting 4 hours.

Because new moon day is the first day of a Chinese lunar month, Chinese lunar month of September 2005 for USA time zones are different from the one for China time zone. 15th lunar day is the Chinese Moon Festival day. Therefore 09/18/05 is the Moon Festival Day in China, but 09-17-05 is the Moon Festival Day in USA.

Moon Festival day is on the 15th moon day of 8th lunar month, which is not necessary a full moon day.
