Japanese Era names Examples

[mastergraywolf]

While the years are easy to understand, what about the months and the days (ie: June 12th 1560 being Eiroku 3, 5th month, 19th day)? The months I suppose can be understood with some listing, as seen below.

EDIT: The answer is "Chinese Calender" (旧暦) ??

Let's use the era of Kōji (弘治) for example:
October 1555 - February 1558

1555 (Kōji 1)
October (month 1) | November (month 2) | December (month 3)

1556 (Kōji 2)
January (month 4) | February (month 5) | March (month #) | April (month #) | May (month #) | June (month #) | July (month #) | August (month #) | September (month #) | October (month #) | November | December

1557 (Kōji 3)
January (month 4) | February (month 5) | March (month #) | April (month #) | May (month #) | June (month #) | July (month #) | August (month #) | September (month #) | October (month #) | November | December

1558 (Kōji 4)
January | February

The new one commenced in Kōji 4, on the 28th day of the 2nd month.
