On a second reading I think I understood better. This may help:

clear
input str8 (France              Italy)
"22/02/09"        "14/06/09
"22/03/09"       "12/7/09

"17/05/09"                "6/9/09"

"09/08/09"        "01/11/09"
"6/9/09"         "29/11/09"

"01/11/09"       "31/01/10"

"31/01/10"        "1/5/10"
end
gen dFrance = date(France, "DM20Y")
gen dItaly = date(Italy, "DM20Y")
gen dF2 = dFrance - dFrance[_n-1]
gen dI2 = dItaly - dItaly[_n-1]
gen t2 = (dFr + dFr[_n-1]) / 2
gen t1 = (dIt + dIt[_n-1]) / 2
gen two = 2
gen one = 1
scatter two dFrance || scatter one dItaly || ///
