The official campaign period is determined by the electoral calendar and generally begins one month before voting day. A campaign's length plays a critical role in the ability of the candidate to get their message out to the general public. Shorter campaign periods typically benefit political incumbents and established parties. Longer campaigns allow lesser-known candidates and parties to better prepare and inform voters. However, a longer campaign period requires more resources to sustain and distribute the campaign's messages to voters.
The length of the campaign depends on the type of election. In general, an Election campaign in India lasts about one month. After the official campaign, it is not uncommon for the contestant to spend a few days preparing for the election, while others choose to work during the official campaign period. Generally, a short campaign period will favor the incumbent and established parties, while a long one will give the less-known party or candidate time to prepare and inform voters.
