Days

A day’s end is not by sunset nor by midnight but by nightfall - when darkness settled.

Dawn marks the beginning of the daytime - when light broke through the darkness

Over time tradition were instituted to guard against breaking the Sabbath.

• The twighlight period - from sunset until three stars are visible is considered the in between - because the exact time the next day starts is not known. Thus sunset is set as the earliest possible defintion of nightfall/evening.
• Traditionally the daytime activities do not start until sunrise.

Between the evenings

• Hebrew bein ha-'arbayim literally means "between the two settings."
  • first "setting" occurs when the sun passes its zenith just after noon and the shadows begin to lengthen,
  • second "setting" is the actual sunset
