The 28 day cycle is the monthly pattern that a woman's body goes through.
The beginning of the cycle, called Day 1, is the day bleeding begins. The flow usually lasts about 3 to 5 days. Usually by Day 7 some of the eggs in the ovaries start ripening. One egg is released from the ovary on about Day 14. The other ripening eggs stop growing and dry up. The time from menstruation to ovulation, may vary from 13 to 20 days in length from one woman to another, but also differs in some women from month to month. Such common circumstances as sickness, worry, physical exertion, and even sudden changes in climate may occasionally upset a regular pattern by shortening it or extending it.
During ovulation the egg travels down the fallopian tube toward the uterus. If a single male sperm unites with the egg while it is in the tube pregnancy begins. If fertilization doesn't take place, the egg cell will break apart in a day or two. About Day 25, hormone levels drop. This causes the lining of the uterus to break down and in a few days it is shed in a menstrual period. Another cycle has begun. This part of the cycle, from ovulation to menstruation, is about the same length in all women. The egg is released consistently 14 to 16 days before the onset of menstruation, regardless of the length of a woman’s menstrual cycle.

Usually a women cycles in 28 days, every 28th day her period starts. It doesn't matter how long it last, it should start again in 28 days. That is not always true of every woman.

The 28 day cycle refers to everything that happens to your uterus: growth of the lining, ovulation, your period, etc. The entire process from the start of one period to the next takes about 28 days.

28 days is close to the average time from one period begins and another begins. This is not the same for every person.
This is why this used to be called moon sickness. About the same time it takes the moon to make its cycle it takes females to make theirs. Superstition used to definitely think the moon had a lot to do with it.

It means that the time from the start of your period to the start of your next period is 28 days. Keeping track of this gives you time to be prepared (buy/carry tampons or pads, etc.) without having to always carry them with you.
