Create Filter Links as in "Last 7 Days"

Like so often, I started out looking here in the forum for what I was trying to do. This time I didn't find a good reference to my exact scenario, so I decided to share it here.

My Goal:
A set of links in my view that look and work something like this:

All | Last 7 days | Last Month | Last 3 Mo. | Last 6 Mo.

HTML in the view (Before Content):

<a href="?all=true">All</a> | <a href="?lastweek=-7+days">Last 7 days</a> | <a href="?lastmonth=-30+days">Last Month</a> | <a href="?lastthreemonth=-90+days">Last 3 Mo.</a> | <a href="?lastsixmonth=-120+days">Last 6 Mo.</a>

Filter Entries (Advanced Settings):

My_Date_Field is "Greater than or equal to" [get param="lastweek"]
My_Date_Field is "Greater than or equal to" [get param="lastmonth"]
My_Date_Field is "Greater than or equal to" [get param="lastthreemonth"]
My_Date_Field is "Greater than or equal to" [get param="lastsixmonth"]

Note:
For the "All" link, I just made up a parameter but didn't create a filter for it since I didn't want it so affect any filters, just show all results. The view ignores it.

Hope this helps someone searching on this down the road... enjoy!
