How do I calculate the number of days between two dates?
Enter both dates in 'Days between dates' mode — the calculator instantly shows the exact count in days, weeks, months, years, and even weekdays only.
Can I find the date X days from today?
Yes — switch to 'Add / subtract' mode, set today as the start date, enter the number of days, and it shows the exact future (or past) date.
Does the calculator count weekdays separately?
Yes — in between-dates mode it shows both total days and weekdays (Monday–Friday) separately, useful for working out business days.
Can I subtract months and years, not just days?
Yes — the add/subtract mode lets you add or subtract any combination of years, months, and days from a starting date.
How many days until a specific date?
Set today as the start date and your target as the end date — the result shows the exact number of days, weeks, and hours remaining.
