find your time zone and read across from the time you need to convert

Hello Philippe, it seems you live in Montreal according to your profile. If that is correct, using the website @Chris_S linked, I was able to figure out that you are -5 hours back from Zulu, also known as UTC time. You might have to do a little math to convert but I will provide an example. An event starts at 2300Z, you would subtract 5 from it because you are -5 hours, this leaves us with 1800z. You will now convert 1800Z to 12 hour time, by subtracting 12, you only need to -12 if it is above the number 12. You are now left with 0600, or 6 AM which would be the time of an event in Montreal time.

Take a look at this link.

Use the map to find which band you live in. The numbers at the bottom show your time zone offset. For example, I am -6 which means I am 6 hours behind ZULU time.

At your place it’s about 2.30 pm. Which makes 7.30 pm zulu.

But how do I know if it’s pm or am?

It is based on 24 hours, so 0000 to 1159 is AM, and then 1200 to 2359 is PM. That shouldn’t matter though, because it is the same time for every region.

So if an event starts at 2300z, I just substract 5 and it gives me 1800z which is 6pm?

Yes, I forgot to mention, after you subtract 5 if it is 1200-2400 is will be PM and then the opposite of the pie will be AM. I just subtract 12 because it helps me get the exact time, but not AM or PM, AM and PM is based of the the furst subtraction.

And how do I do the opposite? Current time to Zulu time?

Just reverse the math. Instead of subtracting 5, add 5.

So 2:50 pm gives me 1950z. Is that correct?

That is correct.

0250+0500= 0750

0750+1200 (Because PM) = 1950.

Yep, I think that is correct.

Last check, 1900z = 2:00pm?
