Mark Zuckerberg and Priscilla Chan's Relationship Timeline

Mark Zuckerberg and Priscilla Chan's meet-cute is straight out of an early 2000s rom-com.

The Facebook founder met his future wife at a college party while waiting in line for the bathroom. In 2010, they moved in together and tied the knot in a top-secret backyard wedding two years later. They've since welcomed three daughters.

Through the incredible highs and tougher struggles, Zuckerberg and Chan have never wavered in their love and support for one another.

"She just treats him like the guy she's in love with, not the same Mark Zuckerberg everyone else fell in love with," author David Kirkpatrick told the New York Times in 2012.

"He was this nerdy guy who was just a little bit out there," Chan told the New Yorker in 2010. "I remember he had these beer glasses that said 'pound include beer dot H.' It's a tag for C++. It's like college humor but with a nerdy, computer-science appeal."

The app is voiced by Morgan Freeman, and notifies the couple of their daughter's movements and speaks in Mandarin when Max is present.

He continued: "We want to help in making the education system better, or improve health.

April 28, 2019: Mark Zuckerberg unveils his new invention that helps Priscilla Chan stay asleep at night

In April 2019, Zuckerberg introduced the Sleep Box, a light filtering tool that helps Chan sleep soundly through the night. Since becoming a mom, Chan has experienced difficulties getting an adequate amount of shut-eye.

"She'll wake up and check the time on her phone to see if the kids might wake up soon, but then knowing the time stresses her out and she can't fall back asleep," Zuckerberg said of his invention. "It sits on her nightstand, and between the hours of 6-7am it emits a very faint light — visible enough that if she sees it she'll know it's an okay time for one of us to get the kids, but faint enough that the light won't wake her up if she's still sleeping," he explained. The tech founder added that because the box doesn't showcase the time, Chan can "just go back to sleep without having to worry about what time it is."

"As an engineer, building a device to help my partner sleep better is one of the best ways I can think of to express my love and gratitude," he wrote.

"That is why we're partnering with DonorsChoose to help teachers apply the latest findings on how students learn best within their classroom practice and funding the individual professional development asks of teachers across the country."

The grant was able to help educators build teacher resource libraries and mental health services. Additionally, the Chan Zuckerberg Initiative granted teachers NeuroTeach accounts.

October 22, 2019: Mark Zuckerberg and Priscilla Chan explain how Facebook Portal helps their kids keep in touch with relatives

When it comes to managing his young daughters' screen time, Zuckerberg and Chan follow a pretty simple rule. There's a cap on screen time for watching TVs and playing on computers — but, if they're using screen-based technology to stay in touch with family, then they're more flexible.

"Facebook makes this product, Portal — it's this great video chat product — and I let my kids use that to communicate with my parents so they can stay in touch with their grandparents easily, their aunts who live across the country," Zuckerberg told Fox News' Dana Perino. "If our daughters want to video chat with their cousins or their grandparents, I think that's wonderful and I think all the research would generally support that."

Ask the dad again in a few years and he may have a different answer. "They're also very young," he added. "I think I'll have more challenges on this as they get older, but our oldest isn't even 4 years old. She'll get there!"

"Well I think, first of all, we don't give them everything," Zuckerberg said. "That's an important piece, but they also just have responsibilities."

"They have chores, they have responsibilities," Chan chimed in. "We also take them to work. Mark and I take both of them to the office to see what we do, how we contribute."
