Birth date and basic biographic data
Key date details
Jimmy Fallon was born on September 19, 1974, in Brooklyn, New York City, New York, United States. Using this birth date, his age can be calculated by subtracting 1974 from the current year and adjusting for whether his birthday has occurred in the current year. No sources publish an exact time of birth in widely accessible public records, so an exact age in days and hours cannot be confirmed without that data.

How to calculate Jimmy Fallon’s age at a given date
To determine Fallon’s age on a specific past or future date, follow these steps. Note that an exact age in years depends on whether the target date occurs on or after September 19 of that year.
- Identify the target date (for example, June 1, 2024).
- Subtract the birth year from the target year (2024 − 1974 = 50).
- Check whether September 19 has occurred in the target year:
- If the target date is on or after September 19, the age is the result from step 2.
- If the target date is before September 19, subtract one from the result in step 2.
- Record the age in years as of that date.
Applied to June 1, 2024, this method yields an age of 49 years (since his birthday had not yet occurred in 2024). Applied to December 1, 2024, the age would be 50 years. This same procedure works for any past or future date when the exact birth date is known.
