Age Calculator DOB & Countdown

Age Calculator DOB & Countdown is a free offline Android app that turns a date of birth into an exact age, and any two dates into a clear answer — in years, months, weeks, days, hours, minutes and seconds. One app replaces a dozen browser date tools. No sign-up, no account, and every calculation runs on your phone.

AGE CALCULATOR BY DATE OF BIRTH
Enter a DOB and get a full chronological age breakdown, the weekday you were born on, and the days left until your next birthday. This is the precise answer to "how old am I" that paperwork usually demands: school and nursery admission age, government and visa forms, passport and ID applications, job and exam eligibility cut-offs, insurance quotes, pension and retirement planning, and sports age groups.

AGE DIFFERENCE BETWEEN TWO PEOPLE
Compare two dates of birth and read the age gap in years, months and days — for couples, siblings, twins, classmates and family trees.

DATE CALCULATOR: DAYS BETWEEN TWO DATES
Count the days, weeks and months between any start date and end date. Track how long until a deadline, exam, wedding, trip, visa expiry, warranty end, lease renewal or anniversary — and how long since a date that already passed.

WORKING DAYS CALCULATOR
Count business days between two dates with weekends excluded — for project timelines, notice periods, delivery windows, invoice and payment terms, and annual leave planning.

ADD OR SUBTRACT DAYS FROM A DATE
Find the date 30, 45, 90 or 180 days from today, or what the date was 10,000 hours ago. Useful for due dates, contract terms, follow-ups and reminders.

LEAP YEAR CHECKER AND DAY OF THE WEEK FINDER
Check whether any year is a leap year, and find the weekday of any past or future date — from a 29 February birthday to a date in 2100.

YOUR AGE ON OTHER PLANETS
See how old you would be on Mercury, Venus, Mars, Jupiter or Saturn. A classroom favourite with students, teachers and space fans.

ZODIAC SIGN FINDER
Enter a birth date to reveal the Sun sign and its personality traits.

COUNTDOWN TIMERS FOR EVERY BIG DAY
Live countdowns to your birthday, New Year, Christmas, Easter, the first day of Spring and the next total lunar eclipse — days, hours, minutes and seconds, updating in real time.

MY SAVED DATES
Save the birthdays and anniversaries of family, friends and colleagues once, and the app keeps every countdown current — your own birthday reminder list, with no calendar sync required. Share any result to WhatsApp, Instagram, Messenger, Telegram or SMS in a single tap.

WHO USES IT
Parents checking school-entry age, students and teachers, HR and payroll teams, freelancers counting billable business days, event and wedding planners, travellers tracking visa and passport dates, astrologers, and anyone who simply wants to know exactly how old they are today. Used in India, Bangladesh, Pakistan, the United States, the United Kingdom, Canada, Australia, Nigeria, Indonesia, the Philippines, Brazil, Egypt and beyond — dates follow the Gregorian calendar, so results are the same wherever you are.

WORKS OFFLINE, LOADS INSTANTLY
Every calculator works with no internet connection. The app is small, opens in a second, and the dates you save stay on your device.
