how many hours till

The query "how many hours till" appears to be incomplete and likely asks how many hours remain until a specific event or time. To provide an accurate answer, I need to know the specific event or time until which the hours should be calculated. For example, if the question is how many hours till 6:00 PM today, the answer would involve subtracting the current time from 6:00 PM and converting the difference into hours and minutes. Please specify the event, date, or time in question to get the precise number of hours remaining.
