Days between dates, without guesswork
This calculator is for questions such as “How many days are between March 1 and June 15?” It shows the counted days plus equivalent weeks, hours and minutes. Endpoint controls let you choose whether the first and last dates should be included.
Inclusive vs. exclusive counting
Different tasks use different conventions. A trip itinerary may count both the arrival and departure dates, while elapsed-time calculations often exclude one endpoint. The toggles make that assumption explicit instead of hiding it.
Need only working days?
Use the Business Days Calculator to exclude weekends and selected holidays.
Common questions
Are weeks rounded?
No. DateTimeWise shows whole weeks plus the remaining days.
What if the end date is before the start date?
The calculator still measures the absolute span and keeps the selected dates visible.
Can I count years and months instead?
Use the Date Difference Calculator when you want a calendar-style answer such as 2 years, 3 months and 5 days.
