How to recover missing Calendar events and categories on iPhone?

My calendar has been wiped clean, all the events I put there disappeared and so have all the categories I created. I tried everything I could find online, I turned off and turned back on the iCloud thing, looked if I had any backup for my calendar on iCloud (unsuccessful), freed up storage, restarted my phone a thousand times but I just can’t get anything back. Could anyone help me out?

Hi,

Syncing issues are the most common cause of missing calendar events, often fixable by refreshing the device’s connection to your accounts.

Refresh Sync: Go to Settings > Apps > Calendar > Sync and select All Events, then drag three fingers down in the Calendar app to refresh.
Toggle iCloud: In Settings > [Your Name] > iCloud, turn Calendar off and on again to force a re-sync of cloud data.
iCloud Web Restore: If events were deleted, visit iCloud.com, click Data Recovery, and select Restore Calendars to roll back to a previous date (available for up to 30 days).
Check Hidden Calendars: Open the Calendar app, tap Calendars at the bottom, and ensure Show All Calendars is selected to reveal any inadvertently hidden categories.

This has happened to me too. 15 years of iphone calendar gone. I cannot find a fix despite having tried 11 different methods. Just another reason to leave apple. They don't care or this garbage wouldn't happen.
