The query "how many minutes" is quite broad. Minutes are a unit of time, with each hour containing 60 minutes. To clarify or answer the question more precisely, it depends on what is being measured or converted—such as minutes between two times, minutes in an hour/day/year, or a conversion between minutes and other time units. Some common facts about minutes for context:

• There are 60 minutes in one hour.
• There are 1,440 minutes in one day.
• The structure of minutes as a unit comes from the division of hours into 60 parts, originally from the division of a day by the Earth's rotation.

If a more specific calculation or conversion of minutes is needed, please specify the context (e.g., between two times, in an hour/day, or converting minutes to another unit). This will help provide a precise and useful answer. Let me know how to narrow down the question for a detailed response.
