10 essential date and time tools: age calculator, date difference, time duration, countdown timer, stopwatch, world clock, time zone converter, day of week finder, workday calculator, UNIX timestamp converter.
Date and time calculations are essential for project planning, event scheduling, travel, and personal organisation. Our free date and time tools help you calculate ages, find date differences, measure time durations, set countdowns, and much more — all without any signup or cost.
Our age calculator gives you exact age in years, months, and days from any birth date, plus days until your next birthday. The date difference calculator shows the exact number of days, weeks, months, and years between any two dates — perfect for project timelines, contract durations, or anniversary planning.
The time duration calculator measures hours and minutes between two times — useful for shift planning, travel itineraries, or tracking work hours. Our countdown timer counts down to any future event (holidays, deadlines, weddings) and updates in real-time. The stopwatch includes lap timing for fitness, cooking, or productivity tracking.
Scheduling international calls or travelling abroad? Our world clock shows current times in London, New York, Tokyo, Sydney, Dubai, Paris, Mumbai, and Los Angeles, updating every second. The time zone converter helps you find the best time for meetings across different regions — essential for remote teams and global business.
The workday calculator counts only business days (Monday-Friday) between dates, excluding weekends — useful for delivery estimates, payment terms, or project scheduling. Our UNIX timestamp converter translates between computer timestamps and human-readable dates, helpful for developers and data analysts.
All calculations process locally in your browser — no data is sent to any server. Bookmark this page for quick access to all your date and time planning needs.
