The calories per day used to calculate daily values are typically 2,000.

To determine the calories per day used to calculate daily values, you need to refer to the reference standard for nutrition information provided by various health organizations. The most commonly used reference standard is the Daily Value (DV) system in the United States.

According to the DV system, the daily values for nutrients, including calories, are calculated based on a 2,000-calorie diet. This means that for a typical adult, the daily value percentages listed on food labels are based on a 2,000-calorie intake.

Therefore, the correct answer to your question is 2,000 calories.
