Kylie Jenner was born on August 10, 1997. To calculate her age in the year 201, which seems to be a typo or an incomplete year, I'll assume you meant a year close to her lifetime such as 2010 or 2015. If the year is meant to be something else, please clarify.

• If the year is 2010, Kylie Jenner would have been 12 or 13 years old, depending on the month.
• If the year is 2015, she would have been 17 or 18 years old, depending on the month.

Kylie was 10 years old when "Keeping Up with the Kardashians" premiered in 2007. She was born in 1997, so her age in any given year can be calculated by subtracting 1997 from that year. Please specify the complete year for a precise answer. Based on the birth year, Kylie Jenner's age in any recent year can be easily calculated.
