input: question: How many months have 28 days? output: "There are seven months that have 28 days in a year: January, March, May, July, August, October, and December.\n\nTo clarify, the Gregorian calendar, which is the most widely used calendar system today, has 12 months in a year. These 12 months are divided into four seasons: winter, spring, summer, and fall.\n\nThe months with 31 days are: January, March, May, July, August, October, and December.\n\nThe months with 30 days are: April, June, September, and November.\n\nThe only months with 28 days are: February (during a non-leap year) and January, March, May, July, August, October, and December (during a leap year).\n\nDuring a leap year, which occurs every 4 years, February has an additional 2 days, making it a 29-day month. This adjustment helps keep the calendar aligned with the Earth's orbit around the Sun, ensuring that the seasons \nremain approximately the same length over time.\n\nI hope this information helps! If you have any other questions, please feel free to ask."
