How should the production capacity of a project be calculated? Is it appropriate to calculate based on 365 days?

Should the standard calculation for production capacity be based on 360 days, 330 days, or 300 days?
Let’s calculate 8,000 hours – these days it’s almost always calculated this way :lol
The above evaluation report is based on 8,000 hours and 333 days; internally, the factory can use 355 days and 8,520 hours to calculate the margin
We calculate a year as 10 months, with 28 days in each month
In the case of a continuous production process, values of 8000 hours, 8200 hours, and 8400 hours are all used; however, design institutes generally use 8000 hours as it is more straightforward for calculation purposes. The heavy chemical industry, especially the petrochemical sector, currently enjoys excellent operational stability, with an average runtime of 8,400 hours. However, some production processes are batch or intermittent, and in such cases it is not easy to make accurate estimates; instead, estimates must be based on the normal operating conditions of the equipment.
11 months of continuous production followed by 1 month of maintenance
This margin is quite large; is the equipment required to be serviced frequently?
Some projects have a high frequency, while others have a very low one; it’s also acceptable to use 11 months as a basis, as our calculations are quite conservative
What are the consequences if the production capacity is designed in a conservative manner?
