For many people, cooking the turkey correctly or dodging political arguments with family members aren't the most stressful parts of Thanksgiving. It's having to share the road with millions of other travelers on the way to Thanksgiving dinner. If you're hoping to make this element of the holiday a little more tolerable in 2019, plan your day with data from Google Maps.

As Travel + Leisure reports, Google Maps recently published a roundup of Thanksgiving travel tips, including the absolute worst times to hit the road. You may think that leaving the day before Thanksgiving will give you a head-start on traffic, but according to Google, Wednesday is the busiest travel day of the week. Congestion peaks between 3 p.m. and 4 p.m. on Wednesday in many parts of the country. If you have no choice but to travel on November 27, plan to leave earlier in the day before roads get too crowded.

It pays to leave the house early the day of the actual holiday. Around 6 a.m., roads will be clear in most major cities, with traffic gradually increasing throughout the morning and peaking as early as noon.

As people who regularly travel for Turkey Day know, getting to dinner on time is only half the headache. Traffic can be just as brutal on the way home. To make the journey as painless as possible, plan to leave first thing in the morning—ideally on Sunday, when most travelers have completed the trip.

Traveling for Thanksgiving is rarely as simple as driving to and from dinner. If you plan on making pit stops along the way, Google has travel information for that as well. According to Google search trends, "ham shops" are busiest at noon the day before Thanksgiving, and outlet malls reach peak traffic around noon on Black Friday. Here are some more stress-free travel tips for the holiday season.
