How often should you sharpen your mower blade?

Grumpty's answer
Every 6 months
Why bother
A dull blade tears the grass and leaves it ragged. A thorough-tier job. Skippable when life's busy, worth it when it isn't.
Why it's a range
Heavy mowing, warm-season grass, or gritty soil wants it every few months.
When to start thinking about it
A few days' warning does it. Grumpty grumbles 5 days out, then leaves you alone. Mark it done and Grumpty sets the next one, every 6 months, so you can go back to forgetting it exists.
Let Grumpty remember it for you
Add it once. Grumpty tracks the date, grumbles when it's due, and rolls it forward the moment you mark it done. No spreadsheets, no sticky notes, no forgetting.
