Tammuz

a corruption of Dumuzi, the Accadian sun-god (the Adonis of the
Greeks), the husband of the goddess Ishtar. In the Chaldean
calendar there was a month set apart in honour of this god, the
month of June to July, the beginning of the summer solstice. At
this festival, which lasted six days, the worshippers, with loud
lamentations, bewailed the funeral of the god, they sat "weeping
for Tammuz" (Ezek. 8:14).

The name, also borrowed from Chaldea, of one of the months of
the Hebrew calendar.
