After three terms in office, Chancellor Angela Merkel is no stranger to election posters. With a budget of 20 million euros, the conservative Christian Democratic Union (CDU) is pinning up some 22,000 placards across Germany. The use of a deconstructed German flag brings out the party's patriotism, while the main focus of slogans is on issues such as security, family and work.

The Social Democrats are keeping it classic with their long-time red, square logo. Posters concentrate on topics such as education, family, pension, investment and wage inequality. At the end of their 24-million-euro campaign, the SPD is planning a final crusade ahead of election day, which still remains under wraps.

More than 5 million euros have been spent on the liberal FDP's poster campaign. With their black and white photoshoot, the FDP have gone for thoroughly modern marketing, with one man at the center: Christian Lindner. Voters, however, will have a hard time reading the text heavy posters. "Impatience is also a virtue," reads the slogan.

The Greens have remained faithful to their cause and focused on classic topics such as the environment, integration and peace. "Environment isn't everything. But without the environment, everything is nothing," says the slogan. A mainstay on all of the posters is the party's sunflower logo.

The prize for most controversial placards goes, without doubt, to the right-wing AfD. From afar, the poster showing a smiling, pregnant woman seems innocent until the slogan becomes legible: "New Germans? We make them ourselves." In another poster, set against the background image of three bikini-clad women, the AfD asks: "Burkas? We like bikinis."

The Left party have certainly given their best to use as many fonts as possible. In a combination of font and wordplay, this slogan one reads: "[Colorful] People. Decisively against right-wing hate." Affordable rents, fairer pensions and an end to arms exports are the main issues for the leftist party.

The stakes are high for Germany's election year. With Chancellor Angela Merkel up for a fourth term and the populist Alternative for Germany (AfD) party attempting to cash in on anti-migrant sentiment, one thing is clear - German politics won't be the same by the end of 2017. Here's a look at the most important dates.

Germany's "super election year" kicked off in the small western state of Saarland, on the French border. Chancellor Merkel's Christian Democrats (CDU) came out on top, snagging over 40 percent of the vote and securing a third term for state premier Annegret Kramp-Karrenbauer (L). The populist AfD will also enter Saarland's parliament for the first time after claiming 6.2 percent of the vote.

State elections in northern Schleswig-Holstein saw Merkel's CDU overtaking the ruling Social Democrats (SPD) in a surprising upset. The CDU, led by top candidate Daniel Günther (above), won 32 percent of the vote while the SPD dropped three points to 27 percent. Anti-immigrant AfD will also enter the Schleswig-Holstein parliament after clearing the 5 percent hurdle.

The CDU pulled off one of it's biggest victories yet, unseating the SPD in its stronghold in North Rhine-Westphalia. The business-friendly FDP also made significant gains and the AfD will also enter parliament after getting 7 percent. As Germany's most populous state with around 18 million residents, the NRW poll is seen as a test run for how the federal election will play out in September.

The 97th day before the election is the cut off date for any party to announce its intention to run for the Bundestag. They have to submit their applications by 6 p.m. to the Federal Returning Officer. Roderich Egeler (above) oversees the election and heads Germany's Statistical Office.

On the 79th day before the election, the parties that are allowed to take part in the election are announced by the Federal Returning Officer. If a party does not agree with decision, it has four days to file a complaint with Germany's Constitutional Court.

Political parties in Germany have until the 69th day before the election to determine which candidates will be running in which constituency. These representatives make up the first vote on Germany's split ballot. Parties must also submit a list of candidates for the party vote on the second half of the ballot.

Smaller parties that filed a suit with the Constitutional Court to be allowed to take part in the election will receive their verdicts today. This option has only been available since the last Bundestag election in 2013. At that time, 11 parties petitioned the court to appear on the ballot - but none were successful.

Unlike other countries, parties in Germany cannot put up campaign posters or run TV ads until 6 weeks before the election. But on August 13, the campaign floodgates open and no lamp post will be safe from the cardboard visages of each party's main candidates.

A little over one month shy of the election, the most important list is compiled - the electoral register or voter list. In Germany, every citizen who is 18 years or older can vote in the general election - meaning there are 61.5 million eligible voters this year.

At this point, all eligible voters should have recieved an authorization certificate in the mail. People who aren't already on the voter list still have time to register. Those who wish to vote-by-mail can request their ballot.

Less than a week to go and preparations are kicking into high gear. Ballots, polling booths and transport boxes start rolling in and election workers are trained. Local authorities must inform voters where they should go to vote. Residents can still register until 36 hours before the election.

The big day has finally arrived. Schools, gym halls and community centers are transformed as people arrive to cast their ballots. Polling stations open at 8:00 a.m. sharp and at 6:00 p.m. they close again. The votes are tallied and the Federal Returning Officer announces the preliminary results that same night.

Only after all of the representative and party votes are counted, the final result is announced. If a candidate did not win his or her constituency, they could still get a seat in the Bundestag if they made the party's regional list.

The newly elected parliament must meet for the first time no later than one month after the election. Afterwards comes the tricky work of coalition negotiations, followed by a secret ballot to elect the next chancellor.

If anyone wants to challenge the validity of the election, they have two months to do so. All voters, the state election overseers, the president of the Bundestag and the Federal Election Commissioner (above) are entitled to appeal the result.
