Quick buttons

These set the amount/unit instantly (you can still change Mode to subtract).

Month/year additions use “same day if possible”. If the target month is shorter (e.g., Jan 31 + 1 month), the result adjusts to the last valid day.

Ready
Pick a base date, choose add/subtract, and click “Calculate”.
