About this calculator
The next birthday calculator finds the next occurrence of the month and day you select, then counts the calendar days remaining. If the birthday is today, the result tells you so.
How it works
A birthday later in the current year is used; if it has already passed, the calculator checks the following year. For 29 February birthdays in a non-leap year, this tool uses 28 February as a practical display convention. Different people or jurisdictions may observe leap-day birthdays differently.
Results use calendar dates in your device's local date context. Daylight-saving changes do not alter the calendar-day count. For legal, medical, financial or official purposes, confirm the relevant rules with the responsible organisation.
