Question

Having a mental block due to caffeine depravation…

If I add two drop-downs to select time in 24-hour (military) format do I put 24 options for hours or 23? In minutes we won’t put 60, but rather 59… But in this case, how does one set a midnight?

<select name="hour">
    <option value="1">01</option>
    <option value="2">02</option>
    <option value="3">03</option>
    ...
    <option value="20">20</option>
    <option value="21">21</option>
    <option value="22">22</option>
    <option value="23">23</option>
</select>

The usual way is prepending a 00.

00:15 for 12:15am
