"date on which" or "date in which"?

[Letícia Naomi]

Hello!

Could somebody possibly tell me which (if any) of the two sentences below is correct, please?

1. He died on the day before the date on which he would compete.

2. He died on the day before the date in which he would compete.

Thanks a lot!
