1. What is the Date And Time Calculator?

The Date And Time Calculator calculates new dates and times by adding or subtracting time intervals (deltas) from a starting date and time. It's useful for scheduling, planning, and time-based calculations.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( DateTime \) — Starting date and time
• \( Delta \) — Time interval to add or subtract

Explanation: The calculator parses the delta string using PHP's DateTime::modify() method, which understands natural language time expressions.

3. Importance of Date/Time Calculations

Details: Accurate date and time calculations are essential for project planning, scheduling events, calculating deadlines, and many business applications.

4. Using the Calculator

Tips: Enter a starting date and time, then specify a delta in natural language format (e.g., "+1 day", "-2 weeks", "+3 months 5 days"). The calculator will compute the new date and time.

5. Frequently Asked Questions (FAQ)

Q1: What formats does the delta accept?
A: The delta accepts natural language expressions like "+1 day", "-2 weeks", "+3 months 5 days", "+1 year 2 months", etc.

Q2: Does it handle daylight saving time changes?
A: Yes, the calculation automatically adjusts for daylight saving time when applicable.

Q3: What's the maximum/minimum date range?
A: The calculator can handle dates from about 1901 to 2038 on 32-bit systems, and a much wider range on 64-bit systems.

Q4: Can I calculate time differences between two dates?
A: This calculator adds/subtracts time from a starting date. For difference between two dates, you'd need a different calculator.

Q5: Does it work with time zones?
A: The calculation uses the server's time zone by default. For time zone support, additional fields would be needed.
