Expert writing Tips

Best practice

When referring to a specific, countable number of days, it is generally more grammatically correct to use "the number of days" instead of "the amount of days".

Common error

Avoid using "amount" when referring to countable items like days. "Amount" is best used for uncountable nouns. Use "number" instead for countable nouns, so prefer saying "the number of days" over "the amount of days".
