Thirteen
Superstition Link
Thirteen is considered unlucky in some cultures, especially when paired with Friday.
Many buildings skip the thirteenth floor due to superstition.
Counting Accuracy
Pay attention to 'teen' sound at the end; it can be confused with 'thirty' when not enunciated clearly.
Please bring me thirteen (not thirty) chairs for the guests.
Not Actual Time
Avoid saying 'thirteen o'clock'; it is not standard as the 24-hour clock resets after twelve.
Instead of 'thirteen o'clock', say 'one o'clock PM' or '13:00'.
