Fussy time vs colic?

Aim
Okay so I can't believe I'm just now realizing this but I'm pretty sure my son is colicky. Beginning at 3 weeks old he cries between 8pm-11pm. It is very predictable & starts and stops at those times exactly. I try EVERYTHING & nothing seems to comfort him for long / if at all. If I do manage to get him to sleep his eyes pop back open after a few mins of appearing to be in a deep sleep and he starts crying again. So, my question is, what is your babies fussy time like? & if they have colic what is that like? (My MIL said if it's colic it usually goes away at 3 months which we are 10 days from 🙌)
