Hi,
you can use the
Excel generator here which will give you something like this:
(2 6) (4 13) (9 3) (5 14) (12 11) (8 7) (10 1)
(6 7) (8 5) (12 14) (11 10) (1 3) (4 9) (2 13)
(7 13) (2 9) (1 4) (12 8) (3 10) (14 11) (6 5)
(13 5) (6 12) (11 8) (1 2) (10 14) (3 4) (7 9)
(14 4) (11 2) (10 5) (6 1) (13 9) (7 12) (3 8)
(4 8) (9 10) (13 1) (7 11) (5 12) (6 3) (14 2)
(9 12) (13 11) (14 6) (3 7) (4 2) (1 5) (8 10)
(1 11) (10 6) (8 13) (4 5) (2 7) (9 14) (12 3)
(10 2) (5 3) (4 7) (14 13) (8 6) (12 1) (9 11)
(12 10) (14 7) (5 11) (13 3) (9 1) (2 8) (4 6)
(3 14) (1 8) (6 9) (2 12) (7 5) (10 13) (11 4)
(5 9) (7 1) (3 2) (10 4) (14 8) (11 6) (13 12)
(11 3) (12 4) (7 10) (8 9) (6 13) (5 2) (1 14)
and so you could make the first column the Saturday matches and the rest of the columns the Sunday matches. Note you should also assign the match between 1 and 8 in round 11 to be on the Saturday, and then every team will play exactly twice on a Saturday.
