I going on my first overnight pack this weekend and will be using my Jet Boil. Question I have is how long does the smaller canister last? I will probably be heating a quart of water, between dinner and breakfast. Will it last one day, two days, or three or more?

You SHOULD get 20 boils out of it. It's all I take on a 4 day trek.

20 boils is a vast over simplification.
If it's cold, windy, or higher elevations you could lose a lot of efficiency. Some pot materials are less efficient than others as well.
If you pack in a wind shield, it will increase how many boils you get.
You can also keep your canister inside your sleeping bag while you sleep to keep it warm, which will help as well.
It should easily last you a three night trip though, with light usage.

At 1 quart per day, I would estimate it will last at least 10 days, being that it is a Jet Boil.  That would include the standard pot, wind screen, elevations up to 7000', and at temps down to 40*F.  

Here's a good way to find out on your own.  Carry a Sharpie and mark the side of the canister every time you use it.  Put double marks on it every time you boil more than the usual water.  I did this with a large canister and got 28 pints boiled from it.

It's a general rule of thumb sheriff treepacker. Of course temp, elevation and quantity of water boiled makes a difference.

So let me clarify... When I'm boiling 2 cups of water at between 8500' and 11,000' at a temp of 58*, I can get 18 1/2 boils.

Should I have asked where he/she was hiking, what they were making for meals and how much TP it took to keep the canister warm?

Zeke, that's exactly how I've done it in the past.

The minimum on the small canister was 18 boils. That was in the Tetons (between 7000' and 11'000') with temps above 40*. The maximum was in MI. ( 800') temps above 40* with 24 boils.

Side note: Zeke, if I had to venture a guess, your profile pic is from Hurricane Pass looking Northeast toward Middle Teton. Am I close?

Exactomundo, wise guy.  I was spoofing a pic GBH used to use with him at Service Falls.  Nice observation.

Why so snarky? I was simply adding vital information to someone who was obviously looking for it. Things like this aren't always so obvious to those who are inexperienced.

With a regular canister stove, I figure on using 20g/day under normal conditions.  Windy and cold will change that number.  Double that for melting snow.

With a Jetboil, I can get by with something more like 15g/day, and that's while still having tea in the morning and cocoa in the evening in addition to two hot meals/day.

Don't need no stinking Sharpie!  I use the flathead screwdriver to just make a tick mark every time I use it.  15-20 boils (at about 1.5 cups of water per boil) is about what I average.  But I just recently started keeping track using this method.

Right, but for new folks some of us have tendency to provide too much information.  In this case the OP would not have suffered any and his question was sufficiently answered, I think.

No harm no foul.

According to Jetboil, the 100g canisters, which are their smallest canisters, will boil approximately 10 liters of water. If you are boiling 1 quarter of water a day, the Jetboil fuel will last about 10 days since 1 liter is a little bit more than a quart.

I get about 4-5 days out of the small canister from jetboil. The MSR cans seem to give me an extra boil or two.

I am getting 18 to 20 600 ml boils out of a small canister.  Generally.

No oversimplification.
