Vaccine min and max duration between shots

Hello,

As the title suggests what should be the minimum and maximum duration between shots?

She had her first round of vaccines on Feb 2nd.

I have an appointment for second round of dhpp shots for my puppy tomorrow(23rd Feb)

Third appointment is on 16th of March but I might have to move to a different place before that. Is it okay to get her third round of vaccines on 13th March?

If not I might have to delay her vaccine until 28th of March. If that is the case, I can push the second vaccine to March 2nd as there is an availability.

Ofcourse, I will call the vet in the morning but her vaccine appointment is before the vet’s office opening time. I just found out about my moving so I am spiraling into confusion. Please help if there’s any vet here or any experienced guys with vaccines. 🙏🏻
