Search Critera for Dates

Search Critera for Dates

Okay..
I have a vacation rental company ... I'm adjust the Layout for display of leads and have 2 questions.
 
Question 1:
One of my fields is Check in Date... It's a date field.
I want the criteria to be check in date within the next 7 days..   I see there is a after Tomorrow formula ${TOMORROWPLUS}
Anyone know how I would write tomorrow Plus 6 days?  or maybe before tomorrow + 6 days
 
Question 2
, I want to be able to set search Criteria between 2 set dates. 
for example..
"Give me all leads with a check in date between Nov 1st and Nov 10th. "

After selecting the field the next pulldown that contains is/ ins’t / comes after / today ect.. Doesn’t contain Between for this date field.. Although other date and time fields such as lead creation date and date do have the “Between” pull down letting you specify between 2 set dates.

 

Anyone help?

 

Thanks..
