Now, according to Game of Thrones Wiki fan page, Jon was born in 281 AL (AL = Aegon's Landing) and Dany was born in 282 AL, so there's actually just one year in age between the pair.
Jon is 8–9 months older than Dany. This comes directly from GRRM. Dany was born roughly 9 months after the Sack, putting Jon's birth at about the time of the Sack up to a few weeks after.
Jon, then, is Daenerys' brother's son, making her his aunt, and Jon her nephew. They're about the same age, though, yes — Dany was born on Dragonstone near the end of Robert's Rebellion, with Jon born shortly after. So, yes, Dany and Jon having sex in the Season 7 finale is actually incest.
In the original book series, Daenerys was married when she was only 13. Drogo's age is listed as 30 in the same script (Jason Momoa was 32 when he filmed "Game of Thrones" in 2010), making him 15 years her senior.
Jon, who is three years younger and half a foot taller, thinks Ygritte is short for her age. Ygritte's most distinctive feature is her thick, shaggy mop of curly bright red hair.
Sansa Stark is two years older than her sister Arya, which means that she's about 20 years old on the show.
The show does not have Joffrey 15 years younger than Robb and Jon. All of the children, heck, all of the characters in the show, are about 3–5 years older than they are in the book. Joffrey and Sansa are about the same age, in both the books and in the show.
He was Aemon Targaryen. And now his watch is ended. He was more than just the oldest living maester. He was the oldest man in Westeros, and lived through more history than Archmaester Perestan has ever learned.

If the HBO prequel series matches the same timeline as the source material, Viserys was only 52 years old when he died.
Daenerys Targaryen transformed into the Mad Queen in the penultimate episode of Game of Thrones, but why did Daenerys go mad? Essentially, the reason Daenerys burned King's Landing to the ground is that she had already lost everyone and everything dearest to her.
In the span of less than seven episodes, Daenerys Targaryen and Jon Snow met, butted heads, formed an alliance and went to bed together, all while dealing with enemies in and outside of Westeros.
Rhaegar is Daenerys' older brother. He was originally married to Elia Martell, with whom he had two children Rhaenys and Aegon Targaryen.
During the wedding, exiled knight Ser Jorah Mormont pledges his loyalty to Daenerys while her benefactor Illyrio Mopatis gifts her three petrified dragon eggs. Daenerys is afraid of her new husband initially, but after learning the Dothraki language, she begins to bond with Drogo and genuinely falls in love with him.

Aegon I is the pinnacle of Targaryen greatness. His name is mentioned so often across the course of the show that book-averters and die-hard fans alike can both recite his history.
