# Clock - label and arrows [closed]

I have 12 circles. How every single circle sign (from 1 to 12). I know only how to sign with my range {a, 0, 2 π - π/6, π/6}, but I need to have numbers 1-12.

Maybe any ideas how I can make 3 arrows?

Graphics[Table[{ColorData["TemperatureMap", 1 - a/(2 π - π/6)],
Disk[{Cos[a + π/2], Sin[a + π/2]}, 0.1],
Text[Style[a, Black], {Cos[a + π/2], Sin[a + π/2]}]}, {a, 0, 2 π - π/6, π/6}]]

• Look up Text[] for adding labels. – J. M. will be back soon Apr 4 '16 at 17:47
• Okay, I eddited, but how to label as 1-12 not pi etc.? – Karol Apr 4 '16 at 19:28
• Maybe try using Table[..., {a, 1, 12}] instead and compute the angle as (2 Pi/12) a. Or by all means, divide the angle by Pi/6 to get the number. Whatever you think is easier. – C. E. Apr 4 '16 at 20:25

{h, m, s} = {1, 24, 52};
ah = π/2 - 2 π h/12 - (2 π) m/720;
am = π/2 - 2 π m/60;
as = π/2 - 2 π Floor[s]/60;
