A countdown timer calculates the time remaining from now until a future date and time, broken down into years, months, days, hours, minutes, and seconds. Used for events, deadlines, product launches, and time-sensitive goals.

Remaining	Total days	Business days
1 week	7 days	5 days
1 month	28–31 days	20–23 days
100 days	100 days	~71 days
1 year	365 or 366 days	~261 days
End of year from Jan 1	365 or 366 days	~261 days

Pro Tip

When counting down to a deadline, display business days separately from calendar days. A 30-day deadline might only give 20 working days to complete tasks — critically different for project planning.
