He was named man of the match against Treviso last Friday, was best man at brother Darren's wedding the following day and turned 22 on Monday.
"I'm thankful to my big brother, Darren, for getting me into rugby," said Hoyland, who signed until 2018.
"He was there to push me to where I wanted to be because he had faith in me to go far."
Edinburgh-born Hoyland, who previously played for Boroughmuir and Melrose, becomes the third player this week to commit to the Pro12 club after new deals for hooker Stuart McInally and centre Chris Dean.
"Since joining the club in 2014, I haven't wanted to go anywhere else," he said.
"You can see how much the club's developed over the last couple of years.
"We're definitely heading in the right direction and it's not a place you'd want to leave when we're achieving all this good stuff."
Hoyland, who scored two tries in the win over Treviso, represented Scotland at youth level and won his first and only senior cap in August against Italy.
"I'm obviously delighted with the one Scotland cap I've got, but I do want to push on for more by playing well for Edinburgh," said the winger who starts against Agen in the European Challenge Cup on Friday.
Head coach Alan Solomons was delighted that Hoyland had committed himself to the club.
"As a talented young Scottish player, he epitomises our vision for Edinburgh," he said.

The 33-year-old Swiss announced he was "not match-fit" as he apologised in person to the crowd at the O2 Arena.
Federer beat Stan Wawrinka 4-6 7-5 7-6 (8-6) on Saturday in a thrilling semi-final lasting two hours and 48 minutes.
It is Djokovic's fourth victory at the season-ending event and he also becomes the first man to win three titles on the trot since Ivan Lendl in the 1980s.
Federer - who has won the tournament six times - confirmed his withdrawal following the doubles final on Sunday afternoon, won by American brothers Bob and Mike Bryan.
"I'm sorry I'm not fit to play," he said. "I hope you understand. I wanted to come out personally and explain.
"I did everything I could. I took pain-killers, had rest until the very end, but I just cannot compete at this level with Novak.
"At my age it would've been a risk.
"It's not that much of a surprise. This back spasm, whatever it might be, it's just not a fun thing to have during the day. It's just uncomfortable. But I'm positive and I'm hopeful that it's going to go away soon."
Tournament organisers arranged two exhibition matches to take the place of the final.
Djokovic defeated Andy Murray 8-5 in a pro set in the first match and the British number one then paired up with John McEnroe to beat Tim Henman and Pat Cash 8-6 in a doubles contest.
Djokovic, 27, who finished the year with only eight defeats from 66 matches, collected the ATP World Tour Finals trophy before his exhibition with the Briton.
"It's clearly not the way I wanted," he said. "It's an incredible achievement, but at this moment it's hard to talk about it. I'm not one of the players that celebrate this particular type of win.
"I have to reflect on the whole season and this trophy is the crowning moment for the efforts this year. I'm very happy to be able to stand here and finish off with a trophy."
Federer is scheduled to join Switzerland team-mate Wawrinka for the Davis Cup final against France next week and said his immediate plan was for "recovery" and then "travelling to France and getting ready for the clay".
He suffered with a back problem in 2013, and there were signs in the closing moments against Wawrinka that he was struggling again.
Federer did not complete his post-match media duties until after 01:00 GMT on Sunday, and missed his scheduled practice session at O2 Arena in the afternoon.
