"Time is too precious to be spent on anything other than kindness. Many blessings of beauty and joy to you and all you hold dear!" she wrote on Instagram, along with a photo of the couple's daughter Emily and son Matthew.
The beloved Jeopardy! host died on Nov. 8 at age 80 after suffering from stage four pancreatic cancer.
In November, it was reported that Trebek was cremated and Jean — his wife of 30 years — was able to take his ashes home. His final resting place is listed as their Studio City, California, home, according to a copy of Trebek’s death certificate obtained by The Blast.
Days after her husband’s death, Jean shared a short message to fans, thanking them for their support during this difficult time.
"My family and I sincerely thank you all for your compassionate messages and generosity,” she wrote on Instagram, alongside a photo of the couple on their wedding day.
"Your expressions have truly touched our hearts. Thank you so very, very much," she continued. "Many Blessings to all, Jean Trebek."
Reflecting on his decades-long relationship with Jean back in January, the television icon told PEOPLE, "I’m pretty satisfied with my life."
"But my wife Jean and I have been together almost 29 years, and I was thinking about President Bush when he died, and all the comments about his life about what a nice guy he is, and how he and his wife had been together 73 years. I thought, oh my gosh … if I’d just met Jean in my 20s we could have had a longer life together," Trebek said at the time.
