I'd answer a bit differently than replies so far. Later monotheist post "merging" of El and YHWH didn't really have space for El's son so they had to treat him as a lesser and then hostile God. Any worship for him was considered bad.

Otoh, just like "Easter" is an echo of an earlier holiday, it just so happens Canaanites, as I understand it, celebrated the end of the storm god's season in spring ... Very similarly to how Passover is observed. With a sacrificed lamb shank bone and some other aspects.
