Weekend cheat day is okay?

Hey Guys, I have a question. This is my first week of working out 1hr to 1hr-30minutes every 4 days a week.

I am 84kg 5'6ft tall, Male, Asian. I usually eat 1 time at night but much more foods consume even when Im full but now I have change my eating routine to 3 times a day since this week.

Monday to Friday I eat less than 1000 calories. But today Saturday, I may have eaten too much I believe over 1800 calories.

Should I just Consider doing 1 day of cheat day just to fulfill my desire for foods?
