From sunrise yoga and a pop-up playground, to a community garden and a pop-up patio, Edmontonians took to some of the city's empty spaces Sunday to reinvent the city.

The city will see just over 17 hours of daylight Saturday, and a local project is hoping to document the different ways Edmontonians are spending their day.

On Saturday, Edmonton will experience its darkest day with nearly 17 hours of night, and a local group is going to track the thoughts and feelings of Edmontonians and their activities during the day through social media.
