I was able to make GNU Screen start counting windows with the number 1 instead of the default 0 with this code in my .screenrc:

# Get rid of screen 0
bind c screen 1
bind ^c screen 1
bind 0 select 10

When I created windows in .screenrc I used screen 1 so that it would first try 1 and then count up if that window number was taken.

120

The solution is to modify ~/.tmux.conf to:

# Start windows and panes at 1, not 0
set -g base-index 1
setw -g pane-base-index 1

Edit: unlike base-index, pane-base-index is a window option, so setw should be used, as @Jogusa pointed out.

    I wish they made this default, its really inconvenient as 0 as at the other side of the keyboard. – Sam Stoelinga Oct 30 '12 at 6:26

    According to my tmux book it shoud be setw in the pane setting: setw -g pane-base-index 1 See the .tmux.conf from book: media.pragprog.com/titles/bhtmux/code/config/tmux.conf – Jogusa Sep 26 '14 at 11:43

    setw is alias for set-window-option or set -w. Altering pane-base-index is a window option. See tmux manpage -> manpages.ubuntu.com/manpages/precise/man1/tmux.1.html – Jogusa Sep 27 '14 at 10:21

    This doesn't seem to change window numbering in interactive window chooser (C-b w). Bug report – matt Oct 22 '17 at 21:01
