The idiomatic meaning of "a herculean task" is a job or undertaking that is extremely difficult, requiring immense strength, effort, and perseverance. It doesn't refer to tasks that simply require physical strength, but rather those that are exceptionally challenging in any respect – be it physical, mental, or logistical.
The expression originates from the Greek myth of Hercules (Heracles in Greek), a hero renowned for his extraordinary strength and courage. As penance for a crime, Hercules was tasked with performing twelve incredibly difficult labors, which included slaying monsters, capturing mythical creatures, and cleaning the Augean stables in a single day. These labors were so arduous that they became synonymous with seemingly impossible feats.
The register of "a herculean task" is neutral to formal. It can be used in everyday conversation as well as in more formal writing.
The expression "a herculean task" is grammatically flexible. It can be modified by adverbs (e.g., "an almost herculean task") or used with different tenses and verb forms (e.g., "they faced a herculean task", "achieving that may be a herculean task"). It can also be negated (e.g., "not a herculean task", "hardly a herculean task").
It sounds unnatural to use the expression in a purely literal sense, such as describing lifting a heavy object unless the context implies an extraordinary level of difficulty beyond the physical. Overusing the expression can also dilute its impact. Applying it to tasks that are merely moderately challenging would be incorrect.

"A herculean task" is almost always used figuratively. While the origin refers to physical feats, the expression now describes any task of immense difficulty, regardless of whether it involves physical strength.
Both phrases describe difficult situations, but "a herculean task" emphasizes the sheer scale and effort required, while "an uphill battle" suggests a continuous struggle against opposition or resistance. A herculean task focuses on the magnitude of the undertaking itself, while an uphill battle highlights the ongoing fight against obstacles.
The most common mistake is using "a herculean task" to describe tasks that are simply challenging, not extraordinarily difficult. To avoid this, make sure the task truly requires immense effort, perseverance, and resources, and that it is far beyond ordinary difficulty. If it's just a tough job, use a less dramatic phrase.
