IRF X-Axis meaning
When eViews draws Impulse Response Functions, the graph starts at "period" 1. Does this period represent the effect of X on Y during the day of the shock or during the first day after the shock? Is therefore period 3 the third day after the shock or the second? This cannot be found anywhere on the documentation and is crucial to a good analysis.

Re: IRF X-Axis meaning
The first period is the shock. You can confirm this by setting the shock to 1.
