Christmas cards are traditionally sent out starting from the first week of December, but it depends on the person. Some people like to send their cards out as soon as possible so they can get their message across and make sure their loved ones receive them before Christmas Day. Others prefer to wait until later in the month, hoping for a more personal touch. Ultimately, it's up to the individual to decide when to send their cards. But whichever way you choose, make sure you put thought and care into your greetings, as your message is what will make the card truly special.
