Finding specific columns and counting in them

Hi,

I would need to count number of specific entries between two columns.
I have columns with different dates in first row:
[TABLE="width: 653"]

[tr]

[TD="class: xl71, width: 85, align: right"]06.01.2017[/TD]
[TD="class: xl71, width: 85, align: right"]04.01.2017[/TD]
[TD="class: xl71, width: 95, align: right"]03.01.2017[/TD]
[TD="class: xl71, width: 88, align: right"]29.12.2016[/TD]
[TD="class: xl71, width: 109, align: right"]28.12.2016[/TD]
[TD="class: xl71, width: 103, align: right"]22.12.2016[/TD]
[TD="class: xl71, width: 88, align: right"]20.12.2016[/TD]

[/tr]

[/TABLE]

there are different values in the columns (e.g. sms or mail)

Then I have defined weeks, e.g. 26.12.2016 to 30.12.2016

I would like to count number of word "sms" in the columns where dates fall between above range. In this case this are only two columns (28.12.2016 and 29.12.2016).
If possible I would also like to define rows, so that it counts only from 1 to 1128 row.

Is there any way to do this?
Thank you

Re: Finding specific columns and counting in them

I am attaching sample file of how data are structured (sheet2) and how I will add week periods and count data for that period (sheet1).
