How Days Until Works
Enter your future date. The calculator uses today as the starting point and shows days remaining. Use "Include last day" to count the target date. The calculator prevents selecting past dates.
Enable "Include time" for countdown precision down to hours, minutes, and seconds, updating every second. Perfect for tracking time until birthdays, holidays, vacations, weddings, product launches, or any upcoming milestone.
Results show days remaining clearly. With time enabled, the countdown updates every second. Use the export feature to generate a shareable link for coordinating deadlines or sharing excitement about upcoming events.
