Note
Can the Year start in May?
This is a common argument against VAT4956 being dated to the year 588 BC. See article Late Start
Note B
the moon became visible behind the Bull of Heaven
When the Moon is first visible it normally isn't that far behind the setting Sun. The stars would not be visible in the twilight sky. This position must be approximated based on what is visible once all the stars can be seen in the western sky, or by the experience of the observer.

.Note C
Moon position 1
the moon became visible behind the Bull of Heaven

The Moon is behind (sets after it) Taurus in 588 BC, in either year the stars of Taurus would not have been visible by the time the Moon had set.
Critics say that the Babylonian year never started as late as May, please read Late Start for an explanation.
Another argument against the year 588 BC is that critics say they the moon would not have been visible on this day. Consider the article New Moon Sightings for a comparison to a new moon sighting in modern times.
