Direct answer
Choosing an expiration sets the time available for the thesis and changes premium, theta, gamma, and volatility exposure. Start with the date by which the expected event or stock move should occur, then select a contract that leaves room for delay rather than starting from the cheapest expiration. More time usually costs more but reduces the need for an immediate move; less time usually costs less but makes timing and late-stage gamma more important.
Option expiration selection: the core structure

Option expiration selection: the variables to compare
More time usually costs more but reduces the need for an immediate move; less time usually costs less but makes timing and late-stage gamma more important. Compare several expirations using the same stock price, strike logic, quote time, and implied-volatility assumptions.
Option expiration selection: the risk that remains
Calendar days are not interchangeable with trading days, and an event can occur after the contract expires. Check the exact expiration and settlement terms, earnings and dividend dates, liquidity, maximum loss, and the exit checkpoint before accepting the contract.
