How many days in advance a booking was confirmed

For Free Raisins bookings confirmed in 2013, extracted from getting booked for dances.

(I think we're generally getting booked even farther out now, though I haven't checked.)

This is a mixed bag for bands. On the one hand, especially for people who are in this professionally, a long booking cycle does give you some job security. On the other hand, it can be hard to know how much time you'll have a year from now, or whether you'll still even be living in that area anymore.

Bringing in money makes this all more complicated. I play dances in my off time, but for many dance musicians this is the main way they earn their living. To make a reasonable wage this means mostly playing bigger events, so when a smaller dance you love wants to book a year in advance you're running a very real risk that a larger event will later ask about the same date. If the smaller dance were willing to book with a shorter lead time that risk would be much lower, and more people could say yes.

I'm not sure how to make this better. Ideas? I don't want to get into a situation where we're booking two years out.
