    Function isSameMinute

    • Check if two dates are in the same minute.

      This function compares two dates and returns true if they fall within the same minute, regardless of seconds or milliseconds.

      Parameters

      • dateLeft: number | Date

        The first date as a Date object or timestamp (number)

      • dateRight: number | Date

        The second date as a Date object or timestamp (number)

      Returns boolean

      True if both dates are in the same minute, false otherwise or if either date is invalid

      // Same minute, different seconds
      const result = isSameMinute(
        new Date(2024, 5, 15, 14, 30, 0),
        new Date(2024, 5, 15, 14, 30, 59)
      );
      // Returns: true

      // Different minutes
      const result2 = isSameMinute(
        new Date(2024, 5, 15, 14, 30, 59),
        new Date(2024, 5, 15, 14, 31, 0)
      );
      // Returns: false

      // Same minute, different seconds and milliseconds
      const result3 = isSameMinute(
        new Date(2024, 5, 15, 14, 30, 15, 500),
        new Date(2024, 5, 15, 14, 30, 45, 800)
      );
      // Returns: true

      // Same minute of hour, different hours
      const result4 = isSameMinute(
        new Date(2024, 5, 15, 14, 30),
        new Date(2024, 5, 15, 15, 30)
      );
      // Returns: false (different hours)

      // Invalid dates return false
      const result5 = isSameMinute(new Date("invalid"), new Date(2024, 5, 15, 14, 30));
      // Returns: false
      • Validates arguments before processing (consistent with library patterns)
      • Returns false for any invalid input (Invalid Date, NaN, Infinity, -Infinity)
      • Accepts both Date objects and numeric timestamps
      • Ignores second and millisecond components in the comparison
      • Requires year, month, day, hour, AND minute to match
      • Uses diffMinutes internally to determine if the minute difference is zero
      • Handles DST transitions correctly
