Your exact age down to hours and seconds. Days between any two dates including business days only. Live world clock for 35+ countries. The date 90 days from today. All instant.
Three date and time calculators for everyday use — your exact age, the difference between any two dates, and the current time worldwide.
Date calculators are the kind of tool you need infrequently — but when you need them, you need them quickly and accurately.
The age calculator does more than just tell you how old you are. It calculates your age as a live ticker (seconds increase in real time), shows your age in all units (total days lived: approximately 10,957 for a 30-year-old), gives your zodiac and Chinese zodiac sign, and shows life milestone statistics — total heartbeats since birth, sunrises seen, and Earth orbits completed.
There is also a Compare Ages mode that calculates the exact age difference between two people. Useful for checking the age gap between siblings, or verifying ages for competitive exam eligibility (many Indian exams have upper age limits stated in years and months).
The date difference calculator is particularly useful for contract and legal work. It calculates the exact number of calendar days between two dates and separately shows weekdays and weekend days. There is also an "add or subtract days" feature — enter a start date and say "30 days from 1 April 2025" and it gives you May 1, 2025, along with the day of the week.
Job applications and exam forms often ask for age as of a specific date. The age calculator has a "calculate as of" feature — instead of calculating age as of today, you can calculate age as of the last day of an exam application, a job posting cutoff date, or any arbitrary date.
Legal and contractual deadlines in India are typically stated as calendar days. A legal notice period is 30 calendar days; a cheque dishonour case must be filed within 30 days of receiving the demand notice. The date difference calculator tells you exactly what date that is.
Remote work and international calls are significantly easier with the world clock. The 48-hour timeline comparison feature lets you drag a time marker and see what time it is simultaneously in multiple cities — so scheduling a 3 PM IST call with someone in London and someone in New York is a one-second check rather than a mental gymnastics exercise.
Anniversary and milestone tracking — wedding anniversaries, company founding dates, sobriety milestones, sporting streaks. The date difference calculator tells you how many days ago something happened, or how many days until something happens next.
For those curious about history: there is a "famous dates" shortcut feature in the date difference calculator that lets you instantly load dates like India's Independence Day (August 15, 1947), Republic Day (January 26, 1950), or the GST launch (July 1, 2017) — and immediately see how many days ago that was.
Leap years are automatically accounted for. The calculator tracks total days lived as an exact count — including all February 29 dates in your lifetime. For the years/months/days breakdown, it uses component subtraction rather than dividing total days by 365, which means the answer is always exactly correct regardless of leap years.
Yes. In the age calculator, there is a toggle between "Today" and "Custom Date." Switch to Custom Date and enter any date — past or future. This is useful for calculating age at a historical event, verifying age eligibility as of an exam cutoff date, or finding out how old you will be on a future date like your next birthday.
IST (India Standard Time) is UTC+5:30. Differences: New York −10:30 (EST), London −5:30 (GMT), Dubai −1:30, Singapore +2:30, Sydney +4:30 (AEST). Note that these change during daylight saving time in those countries — IST does not observe daylight saving. The world clock updates in real time and always shows the current accurate difference.
It depends on the specific month. A 1-month period from January 15 ends on February 15, regardless of how many days are in February. A 30-day deadline is counted as exactly 30 calendar days from the start date. Indian courts and contracts sometimes use "month" differently — always check whether the deadline is stated in "days" or "months" before calculating.
Exact age is calculated component by component: first count complete years from birth year to current year. Then check if the birthday has occurred this year - if not, subtract one year. Then count remaining months, borrowing from the year if needed. Then count remaining days, borrowing from the previous month's length. This accounts for varying month lengths and leap years correctly.
Count all calendar days between the two dates, then subtract the number of Saturdays and Sundays in that range. For precise business day counts in India, you would also exclude public holidays — though holiday lists vary by state and organisation. Our date difference calculator counts weekdays (Mon–Fri) and weekends separately, giving you the business day count without manual counting.
