Astrologically, the Seven of Wands, because it corresponds to the third decanate of Leo, is the time period from August 13 to August 22. In divination, the Seven of Wands combines the activities of the Keys listed in the Tableau [Empress, Sun, Tower, Strength, Emperor] together with ideas of pleasure and love connected with the fifth house in Astrology, the natural house of Leo.
Well Dignified: denotes pleasure in strenuous action; some danger through love affairs or self indulgence; also strength and magnanimity;
adventure; courage in the face of difficulties; influence over subordinates.
lll Dignified: indicates ignorance, pretense, vain-glory, quarrels and wrangling, threats and very determined opposition, especially from subordinates and open enemies.

A. E. Waite

A young man on a craggy eminence brandishing a staff; six other staves are raised towards him from below. Divinatory Meanings: It is a card of valour, for, on the surface, six are attacking one, who has, however, the vantage position. On the intellectual plane, it signifies discussion, wordy strife; in business–negotiations, war of trade, barter, competition. It is further a card of success, for the combatant is on the top and his enemies may be unable to reach him. Reversed: Perplexity, embarrassments, anxiety. It is also a caution against indecision.

Aleister Crowley

The Seven of Wands is called Valour. Energy feels itself at its last gasp; it struggles desperately, and may be overcome. This card brings out the defect inherent in the idea of Mars. Patriotism, so to speak, is not enough.

[…]

This card derives from Netzach (Victory) in the suit of Fire. But the Seven is a weak, earthy, feminine number as regards the Tree of Life, and represents a departure from the balance so low down on the Tree that this implies a loss of confidence.

Fortunately, the card is also attributed to Mars in Leo. Leo is still the Sun in his full strength, but the marks of decadence are already to be seen. It is as if the wavering fire summoned the brutal energy of Mars to its support. But this is not enough to counter-act fully the degeneration of the initial energy, and the departure from equilibrium.

The army has been thrown into disorder; if victory is to be won, it will be by dint of individual valour-a “soldiers’ battle”. The pictorial representation shows the fixed and balanced wands of the last card relegated to the background, diminished, and become commonplace.

In front is a large crude uneven club, the first weapon to hand; evidently unsatisfactory in ordered combat. The flames are dispersed, and seem to attack in all directions without systematic purpose.
(From The Book of Thoth)

Golden Dawn’s Book T

TWO hands holding by grip six wands, three crossed. A third hand issuing from a cloud at the lower part of the card, holding an upright wand which passes between the others. Flames leap from the point of junction. Above and below the central wand are the symbols of Mars and Leo, representing the Decan.

Possible victory, depending on the energy and courage exercised; valour;
opposition, obstacles and difficulties, yet courage to meet them; quarrelling, ignorance, pretence, and wrangling, and threatening; also victory in small and unimportant things: and influence upon subordinates.
