It's really very easy...
Here are the 12 Months from the Phoenician and Hebrew
calendars, with their corresponding Major Arcana cards:
Nisanu (Nissan) Aries : Letter 5 (He): V The Hierophant
Ayaru (Iyar) Taurus : Letter 6 (Waw): VI The Lovers
Simanu (Sivan) Gemini : Letter 7 (Zayin): VII The Chariot
Du'uzu (Tammuz) Cancer : Letter 8 (Heth): VIII Justice
Abu (Av) Leo : Letter 9 (Teth): IX The Hermit
Ululu (Elul) Virgo : Letter 10 (Yod): X The Wheel of Fortune
Tashritu (Tishri) Libra : Letter 12 (Lamedh): XII The Hanged Man
Arach-Samna (Cheshvan) Scorpio : Letter 14 (Nun): XIV Temperance
Kislimu (Kislev) Sagittarius : Letter 15 (Samekh): XV The Devil
Shabatu (Shevat) Capricorn : Letter 16 (Ayin): XVI The Tower
Tebetu (Tevet) Aquarius : Letter 18 (Tsade): XVIII The Moon
Adaru (Adar) Pisces : Letter 19 (Qoph): XIX The Sun
*
If these appear to be out of order to you, that is because when
The Golden Dawn made Aleph=Zero they also moved all the
other cards back by one letter, so that all 22 cards are shifted,
and this was done by them as part of their Magical Kabbalah.

Now, in the order of the 22 Letters, we see the 12 Signs-Months:

Just as we began with Aleph, the "idea" of The Creator, and added
three very important ingredients to make the Signs-Months work,
as the Signs-Months were presented, their were needed additions.
We can see the 7 traditional planets in the sky just by looking up,
and the Phoenician alphabet has 7 Letters to go with the Planets,
which are called Beth, Gimmel, Daleth, Kaph, Pe, Resh, and Taw.
Here is where these Planets appear in the order of the 22 Letters:
1
2 Beth
3 Gimmel
4 Daleth
5 Nisanu (Nissan) Aries : Letter 5 (He): V The Hierophant
6 Ayaru (Iyar) Taurus : Letter 6 (Waw): VI The Lovers
7 Simanu (Sivan) Gemini : Letter 7 (Zayin): VII The Chariot
8 Du'uzu (Tammuz) Cancer : Letter 8 (Heth): VIII Justice
9 Abu (Av) Leo : Letter 9 (Teth): IX The Hermit
10 Ululu (Elul) Virgo : Letter 10 (Yod): X The Wheel of Fortune
11 Kaph
12 Tashritu (Tishri) Libra : Letter 12 (Lamedh): XII The Hanged Man
13
14 Arach-Samna (Cheshvan) Scorpio : Letter 14 (Nun): XIV Temperance
15 Kislimu (Kislev) Sagittarius : Letter 15 (Samekh): XV The Devil
16 Shabatu (Shevat) Capricorn : Letter 16 (Ayin): XVI The Tower
17 Pe
18 Tebetu (Tevet) Aquarius : Letter 18 (Tsade): XVIII The Moon
19 Adaru (Adar) Pisces : Letter 19 (Qoph): XIX The Sun
20 Resh
21
22 Taw
There are 5,040 ways, mathematically, to put any 7 things in order:
1 x 1 = 1
2 x 1 = 2
3 x 2 = 6
4 x 6 = 24
5 x 24 = 120
6 x 120 = 720
7 x 720 = 5,040
No traditional text exists to say what order the Planets appear in the
alphabet, and so most systems rely on Kabbalah. Kabbalah is unique.
Think for yourself which planet may (should) go where. You decide.
For myself what I did was look out the window, and in order of their
distance from Earth: Moon Venus Mars Mercury Sun Jupiter Saturn.
That's my order for the Planets, and even if I am wrong, I am happy.
Plus, I can look up to the heavens and see that they are actually so.

Since we now know which Letters go with the Planets and Signs-Months,
we can see that along with Aleph there are 2 other Letters for Elements.
Letter 1 is Aleph, traditionally given the attribute of Air (Mind).
Letter 13 is Mem, traditionally given the attribute of Water (Body).
Letter 21 is Shin, traditionally given the attribute of Fire (Soul).

And so here are all 22 Letters with their corresponding attributions:
1 ALEPH
2 Beth
3 Gimmel
4 Daleth
5 Nisanu (Nissan) Aries : Letter 5 (He): V The Hierophant
6 Ayaru (Iyar) Taurus : Letter 6 (Waw): VI The Lovers
