It looks like you're asking about "an hour annually." Let me clarify what that means:

What is "an hour annually"?

• "An hour annually" means one hour per year.
• For example, if you spend one hour every year doing something, that is "an hour annually."

Examples:

• If you work 1 hour annually, you work just 1 hour total in a whole year.
• If a service or subscription costs $12 annually, that's $1 per month, or roughly $0.083 per hour if you think about it in terms of time.

Why might this term be used?

• Sometimes people talk about time or resources allocated on an annual basis.
• For instance, if a machine runs only 1 hour annually, it means it operates very rarely.
