Why does Harry never remember his parents death on the anniversary day?

If my parents died on Halloween, I would be even আরো freaked out and scared out of my wits. Its my পছন্দ holiday but it wouldn't be after that. Maybe he talks to them in private অথবা something. Scariest night of the year. I dont know-maybe he figures all kinds of weird things can happen? Just a guess.

Because, I suppose, Harry had no idea that the incident happened on the night of Halloween. Since the book is written in Harry's point of view we find out about things the same time Harry does. Which means that us finding out about Lily's and James's death in the 7th book means that Harry hadn't known about it before either. That's quite logical, he was 1 when they died and it's ব্যক্ত in the Sorcerer's Stone that asking প্রশ্ন - especially about his parents - was forbidden in the প্রথমপাতা of the Dursleys. From who else would Harry know about it? And generally, since when do we commemorate about the death দিন of people? Our being wants to forget about such awful events as soon as possible, our mind erases the dates of funerals, deaths, divorces and all stuff like that. We don't celebrate their anniversaries as we do with birthdays and weddings. Would make no sense to remind ourselves of something bad, would it?

because harry didn't find out when they died until the deathly hallows, when he sees his parents grave, দ্বারা which time he had already celebreated many halloweens.

some people like to ignore and forget about that shit. I know I would.
