Need clarification on event ticket category

You will see a lot of different categories of tickets mentioned while you go on a certain event ticket. Some may say Gold, Platinum, Silver while others may say Regular, VIP, etc.  All of these are different categories of tickets available for that event with different benefits to them. These benefits or inclusions are always mentioned on the event ticket page. The difference may also be based on the seating and distance. All of this is provided by the organizers of the event.  

What does Early Bird, Phase 1, Phase 2 mean?

Each category tickets are sold in different phases which allows you for entering the same category at different price bands, the early bird is a discounted price for the people who buy in advance, then phase 1 prices are a little more expensive than the early bird and phase 2 are more expensive than early bird & phase 1.

All the ticket holders who purchased tickets in the respective category either an early bird or phase 1 or phase 2 are allowed to the respective category there is no difference in seating/standing for early bird or phase 1 or phase 2.
