Time & Date Calculators
Days Until Date Calculator
Pick a target date and this calculator counts the full days between today and that date, with weeks, weekdays, hours and minutes alongside. Tomorrow returns 1, today returns 0, and a past date comes back as days elapsed. Set your own start date, tick include end day to count the target day itself. All totals are calendar days.
Calculator
How It Works
The calculator subtracts the start date (today unless you set one) from your target date to give the number of days remaining; weeks, weekdays, hours and minutes are that same span in other units, and the target day itself is counted when include end day is ticked.
About This Calculator
What It Does
Count down the days, weeks, weekdays, hours and minutes remaining until any future date, from today or from a start date you choose. Include the end day when the target day itself should count, and a date already past comes back as the days elapsed.
Worked Example
From 29 September 2026 to 25 December 2026: 87 days remaining, which is 12 weeks or 63 weekdays. Ticking include end day makes it 88 days.
Real-World Usage
Count down to holidays, birthdays, weddings, vacation departures, project deadlines, exam dates, or product launches. The weekday estimator helps for business planning.
Local Context
Weekday calculations exclude Saturdays and Sundays (the standard weekend in most countries). In some Middle Eastern countries where the weekend is Friday-Saturday, weekday counts would differ.

Frequently Asked Questions
Does the countdown include today?
No. The countdown shows full days remaining. If your target is tomorrow, it shows 1 day. If your target is today, it shows 0 days. Tick include end day to count the target day itself, which adds 1 day.
What happens if I select a past date?
The calculator will show that the date has already passed and display how many days ago it was.
Can I use this to track multiple countdowns?
This tool is designed for one date at a time, perfect for your most important countdown. You can bookmark the page with a target date parameter to quickly revisit it.
