Question 1

How accurate is the date difference calculation?

Accepted Answer

The calculator is very accurate and accounts for leap years, different month lengths, and daylight saving time changes. It calculates the exact difference down to the second.

Question 2

What if I enter the end date before the start date?

Accepted Answer

The calculator automatically detects this and swaps the dates to ensure the calculation is correct. The result will always show a positive difference.

Question 3

How are years and months calculated?

Accepted Answer

Years and months are calculated as complete units. For example, from Jan 15 to Mar 10 would be 1 month and 24 days, not 1.8 months. This gives you the most practical breakdown.

Question 4

Can I calculate business days only?

Accepted Answer

This calculator shows total calendar days. For business days, you would need to subtract weekends and holidays manually from the total days result.

Question 5

What time zone is used for calculations?

Accepted Answer

The calculator uses your local time zone. If you're calculating dates across time zones, consider the time difference when interpreting results for precise timing.
