Total date = Start date + Days + (Hours + Minutes) / 24
Our calculator provides many benefits:
Takes into account all calendar features: month lengths, leap years, border crossings
Works with any combination of days, hours and minutes
Shows the final date, time and day of the week
Fully adapted version for all devices
Some useful tips for using the calculator:
The calculator adds the specified number of days, hours and minutes to a given starting date and time, automatically accounting for transitions across days, months and years.
Yes, you can specify only days, leaving hours and minutes equal to zero. The time in this case will remain unchanged.
If the sum of hours exceeds 24, the calculator will automatically increase the date by the appropriate number of days. For example, 25 hours = 1 day and 1 hour.
Yes, the calculator automatically takes into account leap years (years divisible by 4, except century years, which must be divisible by 400). A leap year contains 366 days.
Depends on the implementation of the calculator. Usually you can use negative values to subtract time, but it is better to use a special date difference calculator for this.
Specify a start date, enter the number of days in the 'Add days' field, leave the hours and minutes as zero (or enter the current time) and click 'Calculate'.
Yes, you can specify only hours, leaving days and minutes equal to zero. This is useful for calculating the time after several hours.
Specify the start time of the event as the start date and time, add the duration of the event (days, hours, minutes) and get the end time.
Yes, the calculator automatically takes into account that months have different lengths: 31 days (January, March, May, July, August, October, December), 30 days (April, June, September, November), 28/29 days (February).
Yes, the calculator works with any dates - both in the past and in the future. You can calculate the date after a certain time from any starting point.
Specify the current date and time as the starting date, add the project deadline (days, hours) and get the exact deadline date and time.
The calculator will automatically move to the next month based on its length. For example, January 31 + 1 day = February 1 (not January 32).
Yes, enter the start time of work, add the number of working hours and minutes, and get the end time of the working day or shift.
Enter the start date and add 7 days. The time will remain unchanged unless hours and minutes are specified.

The calculator will automatically move to the next month if the resulting date exceeds the length of the current month. For example, January 31 + 1 day = February 1.
Yes, but you need to convert months to days. For example, 3 months ≈ 90 days (the exact number depends on the specific months). For accuracy, it is better to indicate the number of days.
Enter the start date of the vacation, add the duration of the vacation (days) and get the end date of the vacation.
The calculator shows the final date and day of the week. The transition to a week occurs automatically when adding more than 7 days.
