Frequently Asked Questions
How do I calculate the exact number of days between two dates?
Use our Date Difference Calculator by entering your start and end dates. The tool automatically calculates the exact duration in minutes, hours, days, weeks, months, and years. It accounts for leap years and varying month lengths for precise calculations.
What's the difference between calendar days and business days?
Calendar days include all days (weekdays and weekends), while business days typically exclude weekends and holidays. Our duration converter shows total calendar days. For business day calculations, use our dedicated Business Days Calculator tool.
How accurate are the month and year conversions?
Month conversions use an average of 30.44 days per month, and year conversions use 365.25 days per year (accounting for leap years). These are statistical averages - for exact date calculations, use the Date Difference Calculator instead.
Can I calculate age or time until an event?
Yes! Enter your birth date as the start date and today's date as the end date to calculate your exact age. For countdown calculations, enter today's date as start and your target event date as end to see how much time remains.
What are common duration conversion use cases?
Common uses include project planning, age calculations, event countdowns, subscription periods, contract durations, academic semesters, employment periods, and milestone tracking. The tool is useful for both personal and professional time management.
