Frequently Asked Questions
How are month-end birthdays handled?
Month additions clamp the day to the final day of a shorter month. This makes a January 31 start reach a full month on the final day of February.
Is this an official eligibility or legal-age check?
No. It uses calendar dates and a month-end convention, not institution-specific eligibility rules, birth times or local legal definitions. Use valid dates from years 1000 through 9999.
Does Kalika retain my date of birth?
No. The date is used within this tab for the calculation; the tool does not upload it or create a stored profile.
