let me the meaning of ‘matter of days’

In a sentence such as ‘I will let you know in a matter of days’ this means 'I will let you know in the next few days. (It won’t take any longer than that).

THANK YOU BEEEEEEEEEESSS
Also could you exlplain me the distinction between the words ,‘As a matter of fact & In fact’.

… could you explain to me…
“could you explain me” indicates that you want me to give an explanation of you to someone else.

There’s not much distinction and they can often be used interchangeably.

Hi, Gibi!

When your child is born, you have a couple of decades to prepare for college costs. When your child has been graduated from high school and it’s mid-August, it’s a matter of days before that tuition check has to be written.

'In fact" is normally used when you provide a plausible explanation, and then explain why it’s not true. If the plausible explanation has been accepted for a while, one would normally restate that explanation and say, but “as a matter of fact”, here’s the real explanation. Not a big difference, and I had to scratch my head to explain where each is more appropriate. If you use the “wrong” term, people won’t point at you and laugh; your explanation will be a little less persuasive, though.

Thank you steve & bees
but i didn’t get the term’plausible’
Hope you’ll explain

‘Plausible’ describes something that can reasonably be accepted. ‘A plausible explanation’ means an explanation that most people are willing/prepared to believe.
