Calendar for Year 2027 (Israel)

Keep in mind that

• The calendar is based on the Biblical system of observing the new moon in Palestine. Whenever possible calculated dates should be confirmed by actual observations in Palestine. Calculating may have been acceptable prior to today's abilities of observing the new moon in Palestine and then broadcasting it to the whole world, but that is no longer a valid excuse.
• The sighting of the new moon on or after the spring equinox determines the beginning of the 1st month.  The new moon is not visible for approximately two days/nights, 1 Samuel 20:24-27 also hints at the two nights being a celebration in anticipation of the event.
• Then count to the fourteenth day from that moon and you have Passover, from this you can calculate unleavened, and First Fruits / Weeks. But Trumpets, Atonement, Tabernacles, and the Eight Day are determined by the visible new moon in the seventh month, or seventh new moon.
• No month can have more than 30 days in it.
