Introduction to the Online ID Card Number Birthday Extractor
The online ID card number birthday extractor can batch-parse ID card numbers to quickly extract dates of birth, and calculate the solar birthday, lunar birthday, zodiac animal, star sign, and other information, with one-click export to Excel.
This tool uses pure client-side computation and does not upload data, ensuring user privacy and security. By default, the extraction tool uses the lunar calendar to determine the zodiac animal.
It's suited for HR management, data organization, membership system maintenance, user information verification, and similar scenarios, efficiently extracting birthday data from ID card information to improve work efficiency.
ID Card Basics
In an 18-digit ID card number, digits 7-14 are the date-of-birth code, where digits 7-10 are the year, digits 11-12 are the month, and digits 13-14 are the day.
For example, if the middle segment of the ID number is 19900307, the date of birth is 1990-03-07. The tool automatically extracts birthday information based on this encoding rule.
Besides the birthday, an ID card number can also help infer the day of the week, zodiac animal, and star sign, which is handy for statistical analysis and data classification.
