If you mean how Many days are there between a girls periods , there are 28
There can be many reasons for your period to be delayed. The most common reasons for delayed menstruation are stress or ill-health - if you're unwell your body recognises that getting pregnant may be a bad idea so it will delay or skip ovulation, which in turn leads to your period being delayed or it will skip that cycle. Delayed periods are also common if you're in your teens due to cycle irregularity - it takes time to reach a point where you are physically and sexually mature enough to ovulate on a regular basis, and changes to your body as you're going through puberty can have a major effect on your cycles and so result in delayed menstruation. Sometimes periods may seem delayed when they're not - the average menstrual cycle is 28 days but everyone's cycles are different, also it's normal for there to be up to 7 days variation between your cycles, so a few days 'late' isn't really late at all.

Many women's bodies react to stress by delaying ovulation. If you have been going through a lot of stress ovulation may have been delayed (this is your bodies natural way of preventing pregnancy during a difficult time) and delayed ovulation will then delay your period. I've had cycles that are even 25 days longer than usual because of this. So a late period doesn't necessarily mean that you were pregnant. Hope that helps!

Around 28 days but it can be less. Girls usually get it about every 3-4 weeks. But if its your first period sometimes it takes your body time to get used to it so you get it about every 2-6 months depending on your body till it is used to it.
A normal period can be 3-7 days long.
