Ah, but that's not so. For example, if New Year's Day falls on a Saturday, then the NYSE doesn't observe the following Monday as a holiday - happened in 2022, for example.
They also avoid being closed more than 3 consecutive days, which is why they are open for trading on Black Friday (but they do close early!).
When you guys quote salaries in monthly figures.. Is the hourly rate fluctuating month to month based on the number of weekends and holidays? Or it vis a vis some standard amount of work days?
Yearly wage / yearly hours works
Th +10sih comes if you work more than weekly hours, or if you have a day-based contract (i.e. you don't count hours).
Most day-based contracts are written saying "you owe x days to the company in a given year", so a holiday on a weekend becomes irrelevant.
