# Calendar.MatchingPolicy.strict

If specified, the algorithm travels as far forward or backward as necessary looking for a match.

## Declaration

```swift
case strict
```

## Discussion

Discussion For example, if searching for Feb 29 in the Gregorian calendar, the algorithm may choose March 1 instead (for example, if the year is not a leap year). If you wish to find the next Feb 29 without the algorithm adjusting the next higher component in the specified DateComponents, then use the strict option. note: There are ultimately implementation-defined limits in how far distant the search will go.
