The expression "after/before dark" refers to a time of the day when the sun has set and it is dark outside. It means that something will happen or should happen after or before this time. For example, if someone says they will meet you after dark, it means they will see you after it becomes dark outside. If someone says they need to finish a task before dark, it means they need to complete it before the sun goes down and it becomes too dark to see. It is commonly used when planning outdoor activities or for safety reasons.
