String comparison in if condition

I have written a condition
Code:
if [ $hour -gt 12 ] && [ $hour -ne 00 ]

where i am comparing the hour value with 00, can i do that, as i am checking if the hour value in the date is not equal to 00 and then diplaying the time as p.m else in a.m.

Please tell me if i can compare $hour with 00. Is that correct or an error?

Please use code tags as required by forum rules!

You should compare with 0 in integer operations, although 00 works as well. Use double quotes around all operands in your expressions to avoid errors on/with word separators! Your logics seem a bit weird - if a value is greater than 12, it definitely is not equal 0.
