It’s time to mark your calendars—the Smithsonian’s newest and hot-ticketed museum has announced that advance passes for April will be up for grabs on January 4 at 9 a.m. and May passes will be available on February 1.

President Barack Obama presided over the National Museum of African American History and Culture’s grand opening ceremony in September, fulfilling a long-awaited dream for many in attendance. And 600,000 guests have visited the museum since then, according to The Washington Post.

Since the museum opened, visitors require timed entry passes, thanks to the high interest in scoping it out. Advance tickets have been released and claimed through March.

The museum also announced that beginning Monday, guests can try to score same-day passes online, instead of lining up hours before the museum’s opening.

So instead of waiting outside for 9:15 a.m. ticket distributions, people can roll over in their beds at 6:30 a.m. to try and get passes. This change was prompted by cold weather, Beverly Morgan-Welch, the museum’s associate director for external affairs, told The Post.

A limited number of walk-up passes will still be available on weekdays at 1 p.m., but that option is no longer available on weekends due to high visitation.

Also beginning on Monday, non-commercial groups of 10 or more will be able to schedule their visit online up to one year in advance.
