Days Between Two Dates Calculator: Your Ultimate Time-Tracking Companion
Need to know the number of days between two particular dates? Whether it’s counting days for a pregnancy milestone, planning a project due next month, or figuring out how many days until your birthday, the Days Between Two Dates Calculator—also called a “days calculator” or “day counter”—is here to help. This handy Date Calculator and Time Calculator takes the guesswork out of calculating time spans, making it perfect for all sorts of situations, from tracking the Cricket World Cup to knowing how many days have passed since you started a job on September 5th, 1970.
I’ve used this tool myself to determine the resulting date for a project starting on March 29th and due on April 25th, or to count the days between April 24th last year and today. It’s simple: just select dates, hit calculate, and get your answer in days, weeks, or even seconds. It’s like having a personal assistant for counting days from a date—whether it’s a full day, weekdays only, or a chosen time span including weekends like Saturday and Sunday.
What Does This Day Counter Do?
The Days Between Two Dates Calculator finds the exact time between a start date and an end date. It counts every day—including the start date and end date—unless you tweak additional settings. It’s great for:
- Counting down to your birthday or the Lok Sabha elections.
- Tracking a project from start to finish, like one due the following week.
- Calculating days in a pregnancy timeline.
- Finding out how many days are left until Thanksgiving or Independence Day.
Unlike tools with complex drop-down menus or settings links, this calculator keeps it straightforward. It includes weekend days (Saturday and Sunday) and doesn’t exclude holidays like July 4th unless you use a “count business days only” checkbox in related tools.
How to Use Our Days Between Dates Calculator
Wondering how to use the day counter? It’s a breeze:
- Go to the “From field” and pick your start date—say, March 29th—using the calendar icon or arrow keys.
- In the “To field,” select your end date, like April 25th, when your project is due.
- Click “Calculate” to see the calculator result in days, weeks, or other units.
- Check the “include end date checkbox” if you want the last date included (it’s the default setting).
- Hit “Clear” to reset and enter other dates or holidays if needed.
The calculator counts the start date and includes weekends unless you adjust settings to count business days only (Monday to Friday work week). If the weekend falls on your chosen dates, it still gives the same result. No need to mentally subtract or add days—it does the calculation for you!
Understanding Your Result
After selecting dates, the calculator displays the time between them. Here’s what you’ll see:
- Days: Total number of days, including Sundays and Saturdays.
- Weeks: Useful for longer periods like a year.
- Hours/Minutes/Seconds: Precise breakdowns down to 11:59 PM if you need it.
For example, between March 29th and April 25th, you might get 27 days if the “include end day box” is checked. It’s perfect for any chosen consecutive span, and you can change the unit to suit your need.
Real-Life Example
Here’s a table showing the calculator in action:
Start Date | End Date | Result (Days) |
---|---|---|
September 5th, 1970 | June 5th, 2022 | 18,902 days (includes leap years) |
July 4th, 2025 | July 26th, 2025 | 22 days (includes weekends) |
This counts every day between selected dates, not just weekdays. For business days, use a related calculator.
FAQs
Got questions about calculating days between dates? Here are some answers:
- Does it include holidays? No, it counts all days unless you specify “include holidays” in additional settings.
- What about business days? This tool includes weekends; use a Working Days Calculator for Monday-to-Friday counts.
- Can I enter other holidays? Not here, but related tools let you list holidays like Labour Day.
- What if the last date isn’t included? Check the “include end day” box—it’s on by default.
The Gregorian Calendar
This calculator uses the Gregorian calendar, a solar calendar named after Pope Gregory XIII, introduced in 1582. It replaced the Julian calendar and is widely used for official purposes in India and other countries, alongside calendars like the Vikram Samvat or lunar Islamic calendar for religious events like Ramadan.
The Doomsday Rule
Curious about the day of the week for any date? John Conway’s Doomsday rule uses algorithms to calculate it mentally. It relies on “doomsdays” (like 4/4 or 6/6) and anchor days by century (e.g., Tuesday for 2000). For example, 3/14 is a doomsday for March. With practice, you can memorize these, but the calculator shows chosen dates instantly—no need to divide by 12 or count back!

Frequently Asked Questions
Does the calculator include the end date in the count?
Yes, the Days Between Two Dates Calculator includes the end date if you check the “include end day” box, which is enabled by default. For example, from March 29th to April 24th, it counts 27 days with the end date included, or 26 days without it.
Can I calculate business days only, excluding weekends and holidays?
This calculator counts all days, including weekends. For business days (Monday to Friday), use a related Working Days Calculator, which excludes weekends and lets you specify holidays like July 4th or Christmas.
How does the calculator handle leap years?
The calculator automatically accounts for leap years, adding February 29th every four years. For example, it correctly calculates 366 days in 2024, ensuring accuracy for long date ranges.
What date format should I use?
The calculator supports multiple formats, including mm/dd/yyyy (US), dd/mm/yyyy (EU), and ISO 8601 (yyyy-mm-dd). Choose your preferred format via the settings for seamless input.
Can I calculate days in different calendars, like Julian or Hijri?
This calculator uses the Gregorian calendar, standard for most global use. For Julian or lunar calendars like Hijri, used for events like Ramadan, you’ll need a specialized tool.

While this calculator counts all days, a related Working Days Calculator lets you exclude holidays like New Year’s Day or custom dates. Enter up to 50 holidays in the settings.
How accurate is the calculator for large date ranges?
The calculator is highly accurate, even for centuries, as it uses the Gregorian calendar and accounts for leap years. For example, it correctly calculates 18,902 days from September 5, 1970, to June 5, 2022.
Can I use this for time-sensitive events like pregnancy or project deadlines?
Absolutely! It’s perfect for tracking pregnancy (e.g., 280 days from conception) or project deadlines, like from April 1st to May 10th (28 days, including weekends).
Does the calculator account for daylight saving time changes?
No, this calculator focuses on dates, not times, so daylight saving time doesn’t affect results. It counts full days, regardless of time zone changes.
Is there a mobile app or offline version of this calculator?
Our calculator is mobile-friendly and works online. For offline use, try Excel or download a date calculator app from your app store for iOS or Android.
What are common mistakes to avoid when using the calculator?
Avoid these errors: not checking the “include end day” box when needed, using incorrect date formats, or forgetting leap years for long ranges. Always double-check your start and end dates.
