On the 7th day of the 7th month, every year, is the Tanabata Festival in Japan.
Why only then?
It is all based a story from early Japan.

This is the story, one of the many, connected with the Milky Way in the night sky. In Japan it is known as the River of the Sky.

It is the story of two lovers, Orihime and Hikoboshi, who represent the stars Vega, and Altair. They are only allowed to meet on the 7th day of the 7th month, every year, at the River of the Sky.
It is a based on poems in the Manyoshu volume, ‘Collection of Ten Thousand Leaves’.  It can be traced back, in turn, to an old Chinese tale, The Weaver Girl and the Cowherd. The corresponding Chinese festival is the Qixi Festival, of the 7th of the 7th.

The Weaver Girl,  was, of course, a princess, and… was she weaving the pattern of the stars and constellations? Her father grew concerned that in her lonely profession she was not able to meet any young men. He invited the cowherd (who herded the cows of heaven?), to meet her.

The meeting went very well, and in time they fell in love. They were able to marry.
On marriage, however, they neglected their duties.
It was thought best for all if they were separated, and only allowed to meet once a year. On meeting, though, they found themselves on opposite sides of the Sky River. Orihime wept so much and so hard that a flock of magpies took pity, flew down and made her a bridge with their wings.

If it rains on the seventh day of the seventh month, though, the magpies may not be able to come.

Tonight he takes his one journey of the year
             Over the Heavenly River, passing Yasu Beach –
He, the love-lorn Oxherd longing for his maid,
Whom he can never see but once a year,
Though from the beginning of heaven and earth
They have have stood face to face across the Heavenly River

……………………………………………………………………………………….
 Tonight, this seventh night of the seventh moon – 
Strangely it thrills my heart.

People write messages, poems, prayers, and hang them from trees on this day.

 

Astronomically, on this date, the distance between Vega, part of the Harp constellation, and Altair, The Eagle constellation, is bridged by a group of stars called The Coathanger, more properly Brocchi’s cluster.
This arrangement forms a straight line with a few dotted stars above this in the centre.
