Customer First Time Calculation Without Earlier

Hi All,

First of all I'm sorry but this article is a little long but It really confusing thing for me I try to explain clearly
I'm in trouble with Earlier function. It is really significant function but it only works with calculated column and it get me into trouble.

Let's give an example.
I have a dataset like that.

I want to find 2 thing.

1- Customer's first coming date.
I was created a calculated column like that and filter only "1" values on my visuals.
 

First Time = CALCULATE (
    COUNT ( 'Table'[Customer] ),
    FILTER (
        'Table',
        'Table'[Date] <= EARLIER ( 'Table'[Date] )
            && 'Table'[Customer] = EARLIER ( 'Table'[Customer] )
    ))

It is working well when customers have only 1 value for each month but It is not working well if customers have 2 values for 1 month.

2-Find the date if customers coming after 3 years.

3 Year Break = 
VAR a =
    CALCULATE (
        COUNTROWS ( 'Table' ),
        FILTER (
            'Table',
            'Table'[Date] < EARLIER ( 'Table'[Date] )
                && 'Table'[Customer] = EARLIER ( 'Table'[Customer] )))
VAR b =
    CALCULATE (
        COUNTROWS ( 'Table' ),
        FILTER (
            'Table',
           'Table'[Date] < EARLIER ( 'Table'[Date] )
                && 'Table'[Date] >= EDATE ( EARLIER ( 'Table'[Date] ), -36 )
                && 'Table'[Customer] = EARLIER ( 'Table'[Customer] )))
RETURN
    IF ( ISBLANK ( a ) || b > 0, 0, 1 )

But again it is not working well when there is 2 record for a month.
In Example:

As I understand doing this things on column is not working for me because my reqierment is dynamic and when we do that on column It became static.

The point I ask for help is that I want to create these calculations as Measure
