* Bhí páirtí agam: This is a straightforward translation, meaning "I had a party." It's a good general option.
* Cheiliúir mé páirtí: This translates to "I celebrated a party," which implies a more formal or significant event.
* Rinne mé páirtí: This translates to "I made a party," which is a less common phrasing but can be used to emphasize the effort put into organizing the party.
The best option will depend on the context. For most casual situations, Bhí páirtí agam is perfectly acceptable and understandable.
