Zodiac, Birthstone and Generation Explained

Your zodiac sign is determined by your birth month and day, following the traditional Western system with 12 signs from Aries (March 21) to Pisces (March 20). Your birthstone is the gemstone associated with your birth month — January gets Garnet, July gets Ruby, and so on. Your generation is based on your birth year: Silent Generation (before 1946), Baby Boomer (1946–1964), Gen X (1965–1980), Millennial (1981–1996), Gen Z (1997–2012), Gen Alpha (2013+).

Dog Years — The AVMA Formula

The old "multiply by 7" rule is inaccurate. The American Veterinary Medical Association (AVMA) formula accounts for the fact that dogs age faster in early life. The first two years count as 10.5 human years each (21 total), and each year after that equals 4 human years. A 10-year-old human is 53 in dog years using this formula.

Birthday Countdown — Never Miss Another Birthday

The countdown shows exactly how many days, hours, minutes, and seconds remain until your next birthday — ticking live every second. If your birthday is today, the counter immediately resets to 365 days.

Age Between Two Dates

The Between Two Dates tab accepts any start and end date and shows the exact difference in all six formats. Useful for calculating project durations, time until a deadline, wedding anniversaries, contract periods, or any other date-to-date interval you need to measure precisely.
