Donna Mills is an American actress best known for starring as Abby Cunningham on Knots Landing and as Laura Denby on the CBS drama series written and created by David Jacobs. As of today in 2025, she is 84 years old. She was born on December 20, 1940, in Chicago, Illinois, which establishes her age at any given date by simple subtraction of years while accounting for whether her birthday has passed in the current year. The following explains her birth year, how to determine her age today, notable career milestones, and reliable sources for verification.
How to calculate Donna Mills age today
To determine Donna Mills age on any given day, subtract her birth year from the current year and adjust by one if her birthday later in the year has not yet occurred. Because her birthday is December 20:
- If today is on or after December 20, her age equals the current year minus 1940.
- If today is before December 20, her age equals the current year minus 1940 minus one.
For example, on December 19, 22025, she would be 84; on December 20, 2025, she turns 85. On June 2025, she remains 84 because her December birthday has not occurred. This calculation method applies consistently across years and is useful for status clarification and timeline verification.
