Days Between Two Dates

Calculate the duration between any two dates

How It Works

Our countdown calculator determines the exact number of days between today and your target date using precise date arithmetic. The calculation uses your local timezone by default, ensuring accurate results regardless of where you are.

Leap years are automatically handled. If your countdown spans February 29th in a leap year, that day is correctly included in the count.

Daylight saving time (DST) transitions don't affect the day count. While clocks may spring forward or fall back, our calculator counts whole calendar days, not hours.

Business days mode excludes Saturdays and Sundays from the count, giving you the number of working days until your target date. This is useful for project deadlines and work-related planning.

Results update in real-time, showing days, hours, minutes, and seconds remaining. Share your countdown with a unique link or export it to your calendar.

What Is a Day Counter?

A day counter (also called a date calculator or countdown calculator) is a tool that calculates how many days until a specific date or how many days since a past date. When you ask "how many days until Christmas?" or "how many days until my birthday?", a day counter gives you the exact answer instantly.

Unlike simple calendar counting, our day counter handles all the complexities automatically: varying month lengths (28, 29, 30, or 31 days), leap years every four years, and timezone differences around the world. Whether you're counting down to a holiday, tracking days since an important milestone, or planning ahead for an event, knowing the exact number of days helps you prepare and stay organized.

How Many Days Are in a Year?

A standard year has 365 days, while a leap year has 366 days. Leap years occur every 4 years (with some exceptions for century years) to keep our calendar aligned with Earth's orbit around the sun. Our calculator automatically accounts for this when computing how many days until your target date.

How Many Weeks Until a Date?

To find how many weeks until a date, simply divide the number of days by 7. For example, if there are 42 days until an event, that's exactly 6 weeks. Our calculator shows you both the day count and can help you think in terms of weeks for longer-term planning.

How many days are in a year?

A regular year has 365 days, while a leap year has 366 days. Leap years occur every 4 years (like 2024, 2028, 2032) to account for the extra quarter-day it takes Earth to orbit the sun. Our calculator automatically factors in leap years when calculating how many days until your target date.

Does the countdown include today?

By default, the countdown does not include today. You can toggle the "Include today" option to count today as one of the remaining days.

Why is my result different from another site?

Differences may occur due to timezone settings, whether today is included in the count, or business days vs calendar days. Check your settings to match the calculation method.

How do you handle leap years?

Our calculator automatically accounts for leap years. February 29th is included in calculations when applicable, ensuring accurate day counts across all years.

What about daylight saving time (DST)?

The calculator uses your local timezone and automatically handles daylight saving time transitions. The day count remains accurate regardless of DST changes.

How many months until a specific date?

While our main calculator shows days, you can use the "Days Between Two Dates" feature to see an approximate month count. As a general guide, divide the number of days by 30 for a rough month estimate, or by 30.44 for a more precise calculation (since the average month length is 30.44 days).
