Differences in the year tell us much about the creator of each. Satan's year is solar only. Yahweh's year is luni-solar - based on the sun and the moon. Remember, Yahweh created TWO lights, the sun and the moon (see Yahweh Created Time) to control (rule) time.

Genesis 1:16
And Yahweh made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also.

Yahweh uses BOTH lights to determine His months and years. The moon is the sole determinate for the months, but BOTH determine the year. This is because the year is made up of 12 moons (months). But if that causes too much drift, the sun will overrule and require an additional (13th) month. The barley needs to be ripe for the new year to start. This is a function of the sun warming the earth sufficiently for the harvest.

Satan's year starts just after the winter solstice (winter in the northern hemisphere). Satan starts his year with winter, which connotes "death". This is appropriate, since he is the death god. Yahweh ends his year with death (winter) at the end - where it belongs.

Yahweh's year starts in the spring, when everything is young and starting to grow. The seasons of spring, summer, fall and winter as a type (example) of man's life. Spring is the start of life as everything starts to grow (spring up out of the earth). Yahweh starts His year with LIFE, while Satan starts his year with DEATH.

"Spring" is the "beginning" or "break" as in break-fast or start.

1 Samuel 9:26
And they arose early: and it came to pass about the spring of the day (break of day, dawn), that Samuel called Saul to the top of the house, saying, Up, that I may send thee away.

2 Samuel 23:4
And he shall be as the light of the morning, when the sun riseth, even a morning without clouds; as the tender grass springing out of the earth by clear shining after rain.

A man's winter is when things are dying and denotes the end of his life, the winter of his life. This also typifies the harvest cycle. Spring planting leads to summer and fall harvests and finally, winter death and rest. So it is with the year. Yahweh's year starts with a new moon at the spring equinox and the spring planting. There is a summer harvest of grain and a fall harvest of grapes. These correspond with His plan of salvation and harvests of souls (see HARVESTS OF REDEMPTION).

There is also a readily observable sign in the sky with the moon announcing the new year. The new year moon occurs only once per year, at (Yahweh's) new year, and looks like this, with the two "horns" being level:



Yahweh gave us His instruction for the start of a new year in His word.

Exodus 12:2
This month [passover, in which they left Egypt] shall be unto you the beginning of months: it shall be the first month of the year to you.

Deuteronomy 16:1
Observe the month of Abib, and keep the passover unto יהוה [Yahweh] thy Elohim [god]: for in the month of Abib יהוה [Yahweh] thy Elohim brought thee forth out of Egypt by night.

This sign in the Heavens announces the new year, and the start of abib, at the time of the New Moon closest to the vernal equinox.

Song of Solomon 2:11-13
For, lo, the winter is past, the rain is over and gone; The flowers appear on the earth; the time of the singing of birds is come, and the voice of the turtle is heard in our land; The fig tree putteth forth her green figs, and the vines with the tender grape give a good smell. Arise, my love, my fair one, and come away.
