1.  Saturday, March 24th
The biblical New Year begins with the sighting of the new moon the night before (i.e. Friday night March 23rd). It’s the first day of Aviv (Ex. 12:2), the first Hebrew month of the biblical year. This is not an annual Sabbath, hence, why it has a blue square (and not a red square), but this year it coincides with the weekly 7th day Sabbath (Friday night to Saturday night).

2.  Friday, April 6th
The 14th of Aviv. In ancient times the Passover lamb was slain in the afternoon. This is not an annual Sabbath, hence the blue square. At darkness, though, the biblical day changes (Gen. 1:3-5f.) and 14 Aviv gives way to 15 Aviv, the first day of the Feast of Unleavened Bread, the first annual Sabbath. The Passover Meal is eaten in the evening (Friday night-15 Aviv).

3.  Saturday, April 7th
The first day of the Feast of Unleavened Bread (Lev. 23:7) begins at dark on Friday night and this is when the Passover meal is eaten. It's the first annual Sabbath, hence, the red square. This year it coincides with the weekly 7th day Sabbath (Friday night to Saturday night).

4.  Sunday, April 8th
First Sheaf (aka First Fruits). This is not a Sabbath, hence the blue square, but it was the day that the High Priest waved 'first fruits' of the spring; the barley grain (Lev. 23:9-11), before the Lord, and also, the day of Yeshua's ascension
(Jn. 20:17), the first fruits to rise from the dead (1st Cor. 15:20, 23).

5.  Friday, April 13th
The 7th day of the Feast of Unleavened Bread, the 21st of Aviv (Lev. 23:9). The second annual Sabbath, which begins the evening before.

8.  Thursday, September 27th

2012 Holy Days
reference calendar

The annual Sabbaths are in red squares
and begin the evening before at dark.

We celebrate Hanuka and Purim at the same time that the traditional Jewish community does because both of these festivals aren’t holy days or times, but holidays. Therefore, there’s no biblical need to have their dates line up with the new moon sightings.
