No, it isn’t. Anger usually occurs as an emotional reaction to something that has happened in the present—you have negative feelings toward someone or something because they did something hurtful or offensive in the recent past (or even just a few minutes ago).On the other hand, irritability is more of a feeling that can be present all day long. Sometimes, it doesn’t have anything specific triggering it. It pertains to having a short-temper or being easily annoyed or angered.‍
