Assuming that the date will always appear on the line immediately
preceding a first-level todo (i.e., ->), you could do something like
this...
syn region Lvl1 start=/^\s*-\{1}>/
\ end=/^\d\d\%(\/\d\d\%(\/\d\d\d\d\)\?\)\?:\n\s*->/me=s-1
\ end=/^\s*-\{1}>/me=s-1 contains=Lvl2,Lvl3,Lvl4 fold
syn region Lvl2 start=/^\s*-\{2}>/
\ end=/^\d\d\%(\/\d\d\%(\/\d\d\d\d\)\?\)\?:\n\s*->/me=s-1
\ end=/^\s*-\{1,2}>/me=s-1 contained contains=Lvl3,Lvl4 fold
syn region Lvl3 start=/^\s*-\{3}>/
\ end=/^\d\d\%(\/\d\d\%(\/\d\d\d\d\)\?\)\?:\n\s*->/me=s-1
\ end=/^\s*-\{1,3}>/me=s-1 contained contains=Lvl4 fold
syn region Lvl4 start=/^\s*-\{4}>/
\ end=/^\d\d\%(\/\d\d\%(\/\d\d\d\d\)\?\)\?:\n\s*->/me=s-1
\ end=/^\s*-\{1,4}>/me=s-1 contained fold
set foldmethod=syntax
Note that it's possible to get much fancier with the date pattern to
ensure that something like 99/99/9999, for example, is not recognized
as a date. Also note that I'm assuming you would have only one date
for a top-level entry and any nested entries below it. In other words,
I'm assuming a --> or ---> entry takes its date from the enclosing ->.
This is why the end regexes ignore dates not followed by a newline,
optional whitespace, and a `->'.
