Convertng from 24 hours to 12 hour clock quickly.

Browsing through neowin I found a thread with poll asking whether one likes 12 hour system OR 24 hour system,and if so is that because it due to difficulty to convert it etc..Reading through the post I got a good tip..it is an easy way to convert between 24 to 12 hours quickly.Here is how:

Take the 24 hour time…. take 2 off it. Simple

13 — 3 – 2 = 1pm
14 — 4 – 2 = 2pm
15 — 5 – 2 = 3pm
16 — 6 – 2 = 4pm
17 — 7 – 2 = 5pm
18 — 8 – 2 = 6pm
19 — 9 – 2 = 7pm
20 — 10-2 = 8pm
21 — 11-2 = 9pm
22 — 12-2 = 10pm
23 — 13-2 = 11pm
00 — If ya can’t work that one out, don’t bother with 24hrs :-p

    So by “subtract 10, then 2″, what you really mean is “subtract 12″?

    Are we really that bad at math that we can’t subtract 12? C’mon people.

    Are people really that stupid that they need a table to convert from 24 hour to 12 hour time?

    Oh. My. God. This is ridiculous. Or maybe it’s just me that has been able to convert between 12h and 24h since I was four…

    12:20pm (as in just after noon) would be 1220hours. If you meant it was 20 minutes after midnight, then it would be 0024hours.

    the incorrect time of 00:20 that matt gave for 20 mins past noon is acutally the time for 20 minutes past midnight.

    1.This is really here just to be useful who have never converted the time before; If all you’re saying is “OMG how can u b so stupid 2 not b able to convert the time” thats really not why this is here.
    2. @spud really, does not using AM and PM make you a “gay twat”?
