I went to apply for a job and said to call me in a day or two. Today is the second day and I haven't called yet. Should I call and ask?

As a human resources point of view, under normal circumstances, the landlord did not inform at this time, which is considered inappropriate, and the unit will not inform. However, there are also some situations, such as weekends, or there are many reporting processes in this unit, so it is postponed. Generally, it is better to wait for three days. If there is no notice within three days (excluding weekends), it should be inappropriate or the company is considering it. You might as well ask politely by phone. After all, the company also has recruitment needs.
