A day begins at sunrise not evening

It is held by most modern Jews and Christians that a biblical day begins at sunset/dusk/evening and ends at the next sunset. This is seemingly primarily based on Genesis 1 which has darkness first and then the creation of light, and says "there was an evening and a morning the 1st/2nd/3rd/4th/5th/6th day". However, someone once suggested from some evidences that a day really begins at sunrise and I have been somewhat convinced of this ever since. But from reading the Bible it seems uncertain for sure whether a day begins at sunrise or at sunset, and I could be wrong, and so this post is for us to post evidences for either. I will start off by posting some seeming possible evidences for a day beginning at sunrise:

Genesis 1:4-5
"God divided the light from the darkness. God called the light Day, and the darkness he called Night." 
Here we see that the light/day is mentioned first before the darkness/night. So the light/day comes first?

Genesis/Bereshith 1:5
If a day begins at evening then how long was the first evening/night (half day) and/or day (full day)? (I.e. since there was darkness for ever/eternity before God said "let there be light" the first night/evening would be very much longer than the other 6 days of creation and all the days since?) (Though I guess a possible answer to this is that the night started when the earth was first started to revolve?)

Genesis/Bereshith 1:5
"there was an evening and there was a morning".
This is usually seen to mean evening (to morning) and morning (to evening). But it could mean (morning to) evening and (evening to) morning. (One version/traslation does have "come to be...")

Genesis 1:16
"God made the two great lights: the greater light (sun) to rule the day, and the lesser light (moon) to rule the night." 
Note the sun/day comes before the moon/night. Like the sun/day comes first?

Genesis 7:4
"forty days and forty nights". 
The days first come before the nights.

Genesis 8:22
"seed time and harvest, and cold and heat, and summer and winter, and day and night". 
Yet again the day comes before the night. (Similarly the summer comes before the winter.)

Psalms/Zabur 118:24
We don't sing the song "this is the day the Lord has made" at evening/night do we?
(We don't sing happy birthday at evening/night do we?
We don't open christmas presents at evening/night do we?
We don't weather forecast day's weather at night?)

The Hebrew word for day is yowm/yome/yom which is related to the Ugaritic Jom which is used for the sun. Yom "day, warmth".

Joel 2:31
"sun shall be turned into darkness, and the moon into blood". 
Again the sun comes first before the moon.

Jonah 1:17
"three days and three nights". 
Again the days come first before the nights.

Lamentations 3:23. 
"They are new every morning".
Maybe implies morning is start of new day?

2 Peter/Cephas 1:19
"until the day dawns, and the day/morning star arises".
The *day* dawns or starts at dawn?

Matt 4:2
"40 days and 40 nights".
Again the days come first before the nights.

John 9:4
"... while it is day. The night is coming, when no one can work."
The day comes first before the night?

Mark 16:2
"Very early on the first day of the week, they came to the tomb when the sun had risen." 
Early not late.
An alternative reading of Matt 28:1 has "Now late on the sabbath day, as it began to dawn toward...."
Late on the sabbath not early in the 1st day Sunday?

Acts 27:33
"While the day was coming on, Paul begged them all to take some food, saying, "This day is the fourteenth day that you wait and continue fasting...."

Revelation/Apocalypse 12:1
"a woman clothed with the sun, and the moon under her feet" 
The sun first before the moon.

Messianic/Christian based on biblical:
"in the same way that God wants our stomach empty when the Day of Atonement starts at sunrise on the 10th of the 7th month".

"According to the strict interpretation of the Mosaic law, every day begins with sunrise and ends with sunset" (Ibn Ezra, commentary on Ex. xviii. 14, Jewish Encyclopedia).

Similar to the day/sun coming first before the night/moon, and the summer coming before the winter, the bible also has the land of gold coming first in Genesis 2, and the White horse coming first in Revelation 5.

Jesus is called the day/morning star (Rev 22:16). (Compare the sun of righteousness in Malachi 4:2.)
Job 38:7
"when the morning stars sang together, and all the sons of God shouted for joy?"
and
Isaiah 14:12
Lucifer the morning star
Both imply the world/creation began at "morning".

(Of course there is maybe a problem with the word day meaning either 24 hours or roughly 12 hours daylight.)

Those are just some seeming possible evidences for a biblical day possibly beginning at sunrise rather than at sunset. However, the chapters of Exodus on the passover and unleavened bread week and the gospels on the crucifixion week possibly might perhaps prove I'm wrong? We may try look at them in coming posts.
