Early labor can last a long time, and it's often the hardest part for a partner to know how to help with. Contractions are irregular, there's no clear task to do, and the instinct is often to hover or to ask a lot of questions. Neither one tends to help.
In the early hours, the most useful thing a partner can usually do is keep things calm and normal. Encourage rest if it's nighttime. Keep food and water nearby. Time a few contractions if it helps to track the pattern, but don't feel like it needs constant monitoring. Mostly, be a steady presence rather than a project manager.
As labor progresses and things intensify, that role shifts toward more active, hands-on support: counter-pressure, helping with position changes, or simply staying close. Knowing the difference between these two phases, and giving yourself permission to just be present in the early one, takes some of the pressure off both of you.
