How does the countdown calculator work?
Select a future date and time. HowLongKit compares it with the current time on your device and calculates the remaining days, weeks, hours and minutes. It also estimates weekdays by excluding Saturdays and Sundays.
What can I count down to?
Use it for birthdays, holidays, vacations, exams, project deadlines, anniversaries, launches and other future events. No account is required and the calculation runs in your browser.
Countdown calculator FAQ
Does HowLongKit store the date I enter?
No. In this launch version, countdown calculations happen locally in your browser and entered dates are not sent to a HowLongKit server.
Are weekdays the same as business days?
The weekday estimate excludes Saturdays and Sundays. It does not remove country-specific public holidays, so verify important business or legal deadlines separately.
Which time zone does the countdown use?
The calculator uses the local date and time reported by your device and browser.
