+Date Range Validation (Within 30 Days) in Client Side
+
+This ServiceNow client script provides real-time date validation for form fields, ensuring users can only select dates within a specific 30-day window from today's date. The script runs automatically when a user changes a date field value, providing immediate feedback and preventing invalid date submissions.
+
+The script validates that any date entered in a form field meets these criteria:
+Minimum Date: Today's date (no past dates allowed)
+Maximum Date: 30 days from today's date
+Real-time Validation: Instant feedback as users type or select dates
+User-friendly Errors: Clear error messages explaining the valid date range
+Automatic Field Clearing: Invalid dates are automatically cleared to prevent submission
