The habitual tense refers to verbs that show action occurring repeatedly. The action can occur daily, weekly, or repeatedly over any other period of time.
The habitual tense would be used to say statements like "I wake up at 5:00 daily". Sometimes, the habitual tense is used based on the context of the statement. If someone asks, "Do you want tea?" and you reply, "I don't drink tea," the habitual tense would be used to indicate that you have made it a habit not to drink tea.
