I am looking for a round robin pitch schedule for 20 people 10 weeks where everyone plays everyone at least once. Thanks
-
I should have noted that there are 4 people that play 4 games a night at a table 1 person rotates at the same table so that all 4 people are partnered that night.

Being unfamilar with pitch, I think I may have misunderstood your request. Are you playing rotating partnerships? If you go to the schedules link above and then dial up Whist for 20 players, is the 19 round schedule the type of thing that you are looking for? My reading is that you want 4 rounds per night for 10 weeks, so two copies of the whist schedule is going to give you 38 of the 40 rounds.

thank you for the reply. We have 5 tables of 4 people per night for 10 weeks. The 4 people stay at the same table that night. I need someway to get a 10 week schedule were everyone plays everyone roughly the same amount of times and not some people playing the same people 3 or 4 times.
Thanks again.

So all you need are assignments of the 20 people to 5 tables for 10 weeks? In which case use the following schedule where all possible pairs of players sit together at a table either once or twice.
(18 17 v 7 10) (12 19 v 9 13)(1 4 v 6 3) (15 2 v 8 20) (11 16 v 5 14)
(19 18 v 8 6) (13 20 v 10 14)(2 5 v 7 4) (11 3 v 9 16) (12 17 v 1 15)
(20 19 v 9 7) (14 16 v 6 15)(3 1 v 8 5) (12 4 v 10 17) (13 18 v 2 11)
(16 20 v 10 8) (15 17 v 7 11)(4 2 v 9 1) (13 5 v 6 18) (14 19 v 3 12)
(17 16 v 6 9) (11 18 v 8 12)(5 3 v 10 2) (14 1 v 7 19) (15 20 v 4 13)
(6 4 v 7 8) (13 14 v 9 17)(19 11 v 10 5) (2 3 v 12 15) (18 16 v 1 20)
(7 5 v 8 9) (14 15 v 10 18)(20 12 v 6 1) (3 4 v 13 11) (19 17 v 2 16)
(8 1 v 9 10) (15 11 v 6 19)(16 13 v 7 2) (4 5 v 14 12) (20 18 v 3 17)
(9 2 v 10 6) (11 12 v 7 20)(17 14 v 8 3) (5 1 v 15 13) (16 19 v 4 18)
(10 3 v 6 7) (12 13 v 8 16)(18 15 v 9 4) (1 2 v 11 14) (17 20 v 5 19)
I am still worrying if partnering is important or not. If players are partnered together for the whole night, then I have indicated how each table should be divided, otherwise just ignore the 'v's.

Excellent, thank you!! no partners are not important. the 4 people at a table rotate at that table for 4 games.
