How to write 7th month, 2nd day of year 4714 in lunar calendar?
think carefully before you "tattoo".

4th august 2016 in lunar calendar is: 丙申歲七月初二

the 4714 is based on "黃帝紀元", a dubious "calendar system"; which used 2698 bc as the starting.

as i remembered, i never read any info about it in literatures of yore.

according to the wiki, it was created in 1903. how authentic, and acceptable is in doubt.

if you insist, the above mentioned date in this style is:

黃帝紀元四千七百一十四年七月初二
