The online lottery for the annual White House Easter Egg Roll is open.
Parents with children ages 13 or younger are eligible to enter for free tickets to the annual springtime ritual, held annually on the South Lawn for the past 137 years.
The lottery opened Monday at noon, and will close at noon Thursday. Those interested in tickets can enter the lottery at any point during that time frame.
The Easter Egg Roll is traditionally held the day after Easter, set this year for Monday, April 6.
The White House welcomes about 30,000 people to the event in shifts each year, and features big-name musical guests, sports activities, a story corner, and egg rolling, an event in which children race to roll eggs across the lawn using spoons.
Ever so modern, this year's theme features a hashtag: "#GimmeFive," celebrating the fifth anniversary of First Lady Michelle Obama's Let's Move! initiative.
#GimmeFive encourages Americans to share on social media what they're doing to eat better, be more active and lead healthier lives, according to a release from the White House.
The designs of 2015's souvenir eggs were also revealed Monday.
Four of the eggs are designed in bright colors: sea breeze blue, sunburst orange, petunia purple and spring green, with the stamped signatures of President Obama and the first lady on the backs. The fifth egg, featuring First Dogs Bo and Sunny, comes in natural wood and features the stamped "paw prints" of the dogs.
