Introduction

The Birthday Countdown tracks upcoming birthdays, shows exact days remaining with a live timer, automatically calculates zodiac signs, and saves multiple profiles for future reference. Perfect for ensuring you never miss an important celebration or gift deadline again.

How to Use the Calculator

  • Enter Person's Name: Give the birthday a name for easy identification (e.g., "Mom", "John").
  • Enter Birth Date: Input the month, day, and year. (Year is technically optional, but required to calculate what age they are turning!)
  • View Live Countdown: Watch the days, hours, minutes, and seconds tick down in real-time.
  • Save to Tracker: Click the bookmark icon () to permanently save the profile to your browser's local tracker.
  • Load Instantly: Click on any saved person in your tracker to immediately load their countdown without re-entering data.

How It Works (Core Logic)

The calculator evaluates the person's birth month and day against today's date. If their birthday has already passed this year, it automatically recalculates the countdown targeting next year.

# Next Birthday Logic
This_Year_Birthday = Date(Current_Year, Birth_Month, Birth_Day)

If This_Year_Birthday < Today:
    Next_Birthday = Date(Current_Year + 1, Birth_Month, Birth_Day)
Else:
    Next_Birthday = This_Year_Birthday
