Expert writing Tips
Best practice
When describing a recurring event with a one-day gap, consider the context. If formality is not a concern, "every other day" is appropriate. In more formal settings, "on alternate days" might be suitable.
Common error
Don't confuse "alternative" in this context with a choice between options. "Every alternative day" incorrectly suggests choosing a different day each time, whereas the intention is a consistent, recurring pattern.
