Not in reference to any of the three commanded Feasts (mental celebrations), but an acknowledgment that humility at times does incorporate fasting and vice -versa. We also do well to understand that as mentioned in the last sentence, the Feasts are joyful times for determined reasons: 1) They are in fact appointed mind festivals for the removal of former wickedness through sacrificial slaughtering, leading to renewing and rebuilding thought from the mind of Yahweh Himself. 2) Even the Day of Atonement, a day of “humbling the mind”, is meant to bring utter joy. The totality of Scripture and its Hebraic intent bears forth the true reality that the humbled mind is the mind most pleasing to Yahweh, and therefore the most blessed by Yahweh. (Iyyob 22:29, Psalm 9:12, 10:12, 10:17, 34:2, 34:18, 51:17, 57:15, Isayah 57:15, 66:2, Mattithyah 18:4, 23:12 Yaaclob 4:6, 4:10, I Peter 5:5-6)

Another pivotal consideration is found at Zecharayah chapter 8, verses 18 and 19:
“The word (“matter, cause”; thoughts spoken within; #1697) of Yahweh of hosts (“mass, campaign”; abundance of thoughts within; #6635) came to me [Zecharyah, “Yahweh remembers”; conscious guidance within; #2148] saying, ‘This is what Yahweh of hosts says: The tsowm (fast) in the fourth moon, the fast in the fifth moon, the fast in the seventh moon and the fast in the tenth moon, will become to the house (mindset) of Judah (the “praise” faculty within that is misaligned with the will of Yahweh) times of pleasure and gladness, joyous Feasts!

Therefore, love truth and peace.'”
With a proper perspective of the three commanded feasts one comes to re – alize that other than a debate over whether or not the Day of Atonement is a day of fasting, there is not one single Scripture in the entirety of the word that commands specific days of fasting. For misaligned “praise” (Judah) in the minds of those given over to hated (Amoshyah 5:21) traditions of carnal minded souls, self prescribed “feast” days, the schedule is as such:
1st month – Taanit Becherim – The fast of the firstborn on Abib 14 – The first month of the correct calendar of Yahweh.

If there was a commanded “Rosh Hashanah”, this month would be it;
4th month – Tzom Tammuz – the fast of Tammuz, on the seventeenth day;
5th month – Tishah BTav – a fast to remember “Jewish” tragedies, on the 9th day;
7th month – Tzom Gedaliah – a fast for murdered governor Gedaliah, on the 3rd day of Tishri/Ethanim;
7th month – Yom Kippur – Day of Atonement;
10th month – Asarah B’Tevet – a fast for the fall of Jeruselum, on the 10th day;
12th month – Ta’anit Esther – fast of Esther, on the 13th day And there are even more: The fast of Miriam (Abib)
10, the fast of Aaron (Av 1), the fast of Moses (Adar 7), the fast of Joshua (Abib 26), and the fast of Samuel (Iyyar 28).
