Can I not attend the meeting today? Because I have many works which need to clear before these holidays. And the report cannot not be updated, because most factories was closed

I won't be able to attend the meeting today as I have a lot of work to get done before the holidays, and, moreover, since most factories are closed right now, the report won't be updated until after the holidays.
