Election day refers to the day when general elections are held.
 In many countries, general elections are always held on a Sunday, to enable as many voters as possible to participate, while in other countries elections are always held on a weekday.
 However, some countries, or regions within a country, always make a weekday election day a public holiday, thus satisfying both demands.
 Many countries permit absentee ballots or early ballots to be cast by mail prior to the election, thereby avoiding the problem altogether.

Fiscal policy and monetary policy are the two tools used by the state to achieve its macroeconomic objectives.
 While for many countries the main objective of fiscal policy is to increase the aggregate output of the economy, the main objective of the monetary policies is to control the interest and inflation rates.
 The IS/LM model is one of the models used to depict the effect of policy interactions on aggregate output and interest rates.
 The fiscal policies have a direct impact on the goods market and the monetary policies have a direct impact on the asset markets; since the two markets are connected to each other via the two macrovariables output and interest rates, the policies interact while influencing output and interest rates.
