Excel/Formula in Excel calculating when US Markets would open



I was wondering if there was a way to write out a formula in Excel displaying the time when the US Markets would open. I understand that it would have to take into account weekends being closed and certain national holidays. Again if this isn't possible or even practical, would there be a way for it to import the times from external sources (such as the internet like through yahoo finance?)

Thank you,


ANSWER: I'm missing something. It's 9:00 AM. No formula necessary.

QUESTION: Oh no, not like that, more of the difference from the time now and when the markets would open, i.e. today is Saturday 12:00 PM and markets open on Monday at 9:30 AM, the cell would show 'Markets are closed, they will open in 1 day 21 hours 30 minutes'.
I tried various times to get the formula to work but there was an issue with the formula only showing 6 hours and 1 minute, regardless of the time of the date. Would pasting my formula here help you out with seeing what I'm doing wrong?

Thank you,
