There are seven months that have 28 days in a year: January, March, May, July, August, October, and December.

To 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.

The months with 31 days are: January, March, May, July, August, October, and December.

The months with 30 days are: April, June, September, and November.

The 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).

During 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 remain approximately the same length over time.
