Frequently Asked Questions About Date Calculators

How do I calculate the number of days between two dates?
Select your start date and end date using our Days Between Dates calculator above. The tool instantly shows the total days, along with a breakdown in years, months, weeks, and even hours. You can also choose to include or exclude the end date in your calculation. The calculator handles all month-end complexities, leap years, and varying month lengths automatically.
Does the calculator include the start and end dates?
By default, we exclude the end date (counting method used in most business calculations). However, you can tick the "Include end date" checkbox if you need both dates counted. This is particularly useful when calculating project timelines or rental periods where both the start and end dates are part of the duration.
How are business days calculated?
Our business days calculator automatically excludes Saturdays and Sundays from the count. You can also enable the "Exclude Indian holidays" option to remove national holidays like Republic Day, Independence Day, Diwali, and Holi from your calculation. This gives you accurate working days for project planning and notice period calculations in the Indian context.
Can I calculate my age in months and days?
Yes! Our age calculator provides your exact age broken down into years, months, and days. It also shows your total age in months, weeks, days, and even hours. Plus, you'll see what day of the week you were born on and how many days until your next birthday. This is especially useful for tracking baby ages, planning milestone birthdays, or calculating exact age for official documents.
What is the most accurate way to add days to a date?
Use our Add/Subtract Days calculator by entering your starting date and the number of days to add. The tool handles month-end dates, leap years, and varying month lengths automatically. For example, adding 30 days to January 31st correctly gives you March 2nd (or 3rd in leap years). You can also use quick buttons for common periods like 30, 60, 90, or 180 days.
Are Indian holidays included in business days calculation?
Yes! We've pre-loaded all major Indian national holidays for 2025 and 2026, including Republic Day (26 Jan), Independence Day (15 Aug), Gandhi Jayanti (2 Oct), Diwali, Holi, and more. Simply check the "Exclude Indian holidays" box in the Business Days calculator. You can also add custom holidays specific to your organisation or state.
How many working days are there in a month in India?
On average, a month has approximately 22 working days in India when excluding weekends (Saturdays and Sundays). However, this varies based on the specific month and whether it contains any national holidays. For example, October typically has fewer working days due to Dussehra and Diwali. Use our business days calculator to get the exact count for any date range.
Can I calculate days until a future event?
Absolutely! Use the Days Until calculator to count down to any future date. We've included preset buttons for popular Indian festivals like Diwali, Holi, and national celebrations. The calculator shows days, weeks, months remaining, plus a live countdown in hours, minutes, and seconds that updates in real-time. Perfect for event planning, exam preparation, or vacation countdowns.
How do I calculate a 90-day notice period?
Use the Add/Subtract Days calculator and select today's date (or your resignation date), then add 90 days. The calculator will show you the exact end date of your notice period. Alternatively, use the Business Days calculator if your company counts only working days for notice periods, and enable the "Exclude Indian holidays" option for accurate results.
What date format does the calculator use?
Our calculators display dates in DD/MM/YYYY format, which is the standard format used in India. For example, 15th August 2025 is shown as 15/08/2025. The input fields use your browser's native date picker, which adapts to your regional settings automatically.
