Japanese calendar configuration (UTC+9, epoch 2636 BCE)
Uses the same epoch as the Chinese calendar but with UTC+9 timezone.
The timezone difference can cause different leap month assignments
in rare cases where a new moon falls near midnight.
Before 1888, Tokyo local solar time (UTC+9:19:04) was used.
