From where does this picklist come from. couldnt find anything related on event fields to get these values?

Any ideas?

Possible Suggestion/Solution #1

It would appear the reminder is stored only as a Date Time and a Boolean. So what your seeing appears to be a specialisation of the UI not driven in the usual way from a picklist. I observed that it is also not visible on the Layout editor either. So in answer to your question, sadly I have to conclude there is no specific field for this dropdown, it is purely a UI aid.

What I found apone further investigation was this...

Select ReminderDateTime, IsReminderSet From Event

When the event starts at 11:00 with a 2hr reminder ...

Gives...

Update: You can actually update the ReminderDateTime field with any date/time you want, however the UI will round it to the nearest value in the drop down. Not sure in practice when the reminder will fire, but wanted to add this further observation.
