when will i turn 18
Turning 18 as the civil age of majority is the standard in most of the world today, including Brazil. This page calculates the exact date a person turns 18, with the target-age field locked at 18 and the reference date hidden to keep the focus on that single milestone.
The date comes from adding 216 months to the birth date, independent of today's date: the result only changes if the birth date changes.
Since 2026 is not a leap year, February 29 does not exist that year, and the tool adjusts the target date to February 28 instead of failing the calculation.
For older birth dates, the result shows the milestone as reached and stops counting remaining days, because the target date is long in the past.
It compares the birth date with a reference date and returns the exact civil age in years, months and days. The same engine also powers days lived, next birthday, age difference and future target age calculations.
Because in Brazil civil majority is set at 18 complete years by the Civil Code (Law 10.406/2002, Article 5), which makes that date relevant for documents, contracts and other acts that require full civil capacity.
Yes, but not on this specific page, which locks the field at 18 to answer this exact search directly. The full calculator accepts any target age between 1 and 150, including 21, 30 or any other whole number.
The 18th-birthday date is adjusted to February 28 in years when February does not have 29 days, because the calculation adds 216 months to the birth date and the resulting day has to fit inside the target month.
You will reach that age on January 15, 2028, in 495 days.
