There are -4 business days until January 1.
In the business world, time until a certain date is complete different. Ten business days is two calendar weeks and one month is only twenty days of production. This changes how much time a corporation working off the traditional 9-5 system of time calculation can actually spend on projects or work. This can add a layer of complexity onto time calculations.
An oversimplification of calculating business daysuntil January 1 is counting the number of total days -5 and subtracting the total number of weekends.
