How it's used
Focuses specifically on the expiration of a time limit or a legal obligation rather than the physical decay of an object. It is frequently used for official documents, financial products, or rental agreements. When referring to food or medicine that has gone bad, use 過期 instead.
Examples
When does your credit card expire?
The contract will expire next month.

Common mistake
Learners often confuse 到期 with 過期. While 到期 means the deadline has arrived or the term is ending, 過期 implies that the deadline has already passed and the item or status is now invalid.
