You can't skip breakfast. It's the first meal you eat in the day, no matter when it is.
If you're wondering what happens if you don't eat soon after awaking, the answer is usually not much. For some people it causes overeating behavior later in the day, and other people get some benefits in things like energy and concentration. But there's nothing particularly important in general about what time you eat or how many meals you take in a day.
‘Breakfast’ is the first meal of your day, irrespective of what time you have it!
But, speaking from a conventional point of view, usually people associate having a meal between 7am to 10am as their breakfast.

If you don't eat breakfast you'll experience body weakness. If you keep skipping the former then there's no point in having a heavy lunch you gotta eat something after waking up to avoid weakness
P.S: I had been skipping breakfast for like 2 years I experienced body weakness and some sharp pain in heart periodically.
