Between 6:30 and 7:30 pm for most 2-year-olds who wake up around 6:30. At two they need 11 to 14 hours a day, and that still counts an afternoon nap of an hour and a half or so.

Lights out between 6:30 and 7:30 pm.

Dinner
An hour and a half out leaves room for a bath without rushing.
A late nap is the usual reason bedtime slides at two. If lights out keeps drifting, wake them from the nap a little earlier, by 3:00 at the latest.
Two is the age of "no" and "one more". Give a choice that doesn't matter, like which pajamas or which of two books, and keep the order of the steps fixed.
There's no rush to leave the crib. Most families find the move to a bed goes easier closer to three, and climbing out is the usual reason to switch sooner.
A few weeks of fighting bedtime is common somewhere around two. Hold the same lights out through it. Changing it every night drags it out.
By wake-up time
The same sleep, counted back from four common wake-ups. Lean early on a day they woke up tired or the nap went wrong.

Sleep hours are the American Academy of Sleep Medicine's recommended ranges, which the American Academy of Pediatrics endorses. Every kid is a little different. If you're worried about how your child sleeps, ask their pediatrician. For any age and wake-up time, use the bedtime calculator.
Knowing lights out is the easy part. Nightlight plans the two hours before it: a dinner that fits the energy you have left, then every step, timed back from 7:00.
