Calculate how many days until any date or event online free - no login. Find days between two dates, count down to a holiday, birthday, or deadline, and see weeks and months too.
Calendar views show you dates but not the raw number of days remaining - which is what matters for planning and deadlines. 'The project is due April 15' is vague; '47 working days away' gives actionable perspective.
Enter any future date and instantly see how many days, weeks, and months remain. Optionally exclude weekends to count only business/working days.
Count days until a project deadline or submission date, calculate working days remaining for a sprint or deliverable, count down to an event, vacation, or celebration, calculate days until a subscription renews or a trial ends, count business days until a payment is due, and plan workload around a fixed future date.
The most common question is how many days until a holiday. Enter the holiday date in the target field and the current date will be pre-filled. Results show both total calendar days and working days (excluding weekends).

Common questions about this tool and how to use it.
Christmas is December 25 each year. Enter December 25 of the current year as the target date and the calculator will show the exact number of days, weeks, and months remaining. After December 25, it automatically calculates days until the next year's Christmas. Common date countdowns: New Year's Eve (December 31), Valentine's Day (February 14), Easter (varies by year), Eid al-Fitr (lunar calendar, varies), and Diwali (Hindu calendar, varies).
Working days (business days) exclude weekends (Saturday and Sunday) and optionally public holidays. The basic calculation: count total calendar days, then subtract weekends (approximately 2/7 of total days). For exact working days, use the working days option which excludes every Saturday and Sunday in the range. For project planning, the working days count is the accurate measure of available production time.
31 days: January, March, May, July, August, October, December. 30 days: April, June, September, November. 28 or 29 days: February (29 in a leap year). Leap years occur every 4 years, except for years divisible by 100 (not leap years) unless also divisible by 400 (leap years). 2000 was a leap year. 1900 was not. 2024 is a leap year; 2028 is next.
Calendar days count every day including weekends and holidays. Business days (working days) count only Monday–Friday, excluding weekends. Some definitions also exclude public holidays. Shipping times and legal deadlines often specify business days - '5 business days' can be up to 9 calendar days if it spans a weekend. Payment terms (Net 30) typically mean 30 calendar days unless specified as business days.
Subtract the earlier date from the later date to get the difference in days. The formula in most programming languages: Math.floor((date2 - date1) / (1000 * 60 * 60 * 24)) in JavaScript. In Excel/Sheets: =DATEDIF(start_date, end_date, 'D') or simply =end_date - start_date (formatted as a number). For counting exclusive of endpoints (not counting the start day): subtract 1 from the total. This calculator handles the arithmetic automatically.
