Frequently Asked Questions
How do time zone conversions work?
Time zones are offset from UTC (Coordinated Universal Time). For example, EST is UTC-5, PST is UTC-8. When converting, add or subtract hours based on the offset difference.
What is a Unix timestamp?
A Unix timestamp counts seconds since January 1, 1970 (UTC). It's a standard way to represent time in programming, making calculations and comparisons simple and timezone-independent.
What is the Pomodoro technique?
The Pomodoro technique is a time management method: work for 25 minutes, then take a 5-minute break. After 4 cycles, take a longer 15-30 minute break. It improves focus and prevents burnout.
How do I calculate the difference between two dates?
Date difference calculators compute the exact time between dates in years, months, weeks, days, hours, minutes, and seconds. Useful for age calculation, project planning, and countdowns.
