1. What is Time Addition?

Time addition calculates a new date and time by adding a specified duration (in hours) to a given start time. This is useful for scheduling, project planning, and time management applications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Start Time — The initial date and time
• Duration — The number of hours to add
• New Time — The resulting date and time

Explanation: The calculator converts hours to seconds and adds them to the start time, automatically handling day transitions and date changes.

3. Importance of Time Calculation

Details: Accurate time calculations are essential for project scheduling, meeting planning, deadline tracking, and any application that requires precise time management across multiple days.

4. Using the Calculator

Tips: Enter the start date and time in the format provided, and specify the duration in hours (can include decimal values for partial hours). The calculator will automatically compute the new date and time.

5. Frequently Asked Questions (FAQ)

Q1: Can I add durations longer than 24 hours?
A: Yes, the calculator automatically handles durations that span multiple days, weeks, or even months.

Q2: Does the calculator account for daylight saving time?
A: The calculation is based on the timezone of the input datetime. Timezone conversions should be handled before using this calculator.

Q3: Can I add minutes or seconds instead of hours?
A: This calculator specifically adds hours. For minutes or seconds, convert them to hours (e.g., 30 minutes = 0.5 hours).

Q4: What format is used for the result?
A: The result is displayed in YYYY-MM-DD HH:MM:SS format for clarity and precision.

Q5: Can I use this for subtracting time?
A: To subtract time, enter a negative duration value (though the input currently restricts to positive values for simplicity).
