What does ``tomorrow'' mean?

`But really you should have a lady's maid!'

`I'm sure I'll take you with pleasure!' the Queen said. `Twopence a week, and jam every other day.'

Alice couldn't help laughing, as she said, `I don't want you to hire ME -- and I don't care for jam.'

`It's very good jam,' said the Queen.

`Well, I don't want any TO-DAY, at any rate.'

`You couldn't have it if you DID want it,' the Queen said. `The rule is, jam to-morrow and jam yesterday -- but never jam to-day.'

`It MUST come sometimes to "jam to-day,"' Alice objected.

`No, it can't,' said the Queen. `It's jam every OTHER day: to-day isn't any OTHER day, you know.'
