Could we use technology to tell us whether this month it will be 29 moon days or 30 moon days?

In other words, is there a way to predict precisely whether the moon will be 29 days or 30 months in advance or even years in advance?

I'm almost positive we can predict that, you should be able to find it on an astronomy website somewhere, maybe if you do a Google search for 'Lunar Calendar' you will find it.

Sorry dude, I asked, I was told you can not do it, literally, there is no way on earth you can predict the number of days in a given moon month ahead of time, it is simply not possible, this is the reality that you have to accept.

We have gone a long distance in astronomy, cosmology, botany, zoology, computer sceince, medical sceince, mathmatics, mechanics, biochemistry, electrical engineering, physics, chemistry, but it is very unfortunate that we can not know ahead of time by months or years the number of days in a given moon month.

This is the reality that we have to accept.

lol, who said they didn't accept it? Anyways however many moon days their are isn't really a big deal.

I wonder what is so difficult about knowing in advance if next moon month will be 29 days or 30 days?
