6. Provide the date of the event. Depending on how formal you want the invitation to be, you can either write the date out completely, as in "Thursday, the eleventh day of May" or keep it short such as, "Thursday, May 11." Writing it out is the more formal way to write the invitation.
7. Write the time of the event in full. Include words such as, "in the morning" or "in the evening" if the event purpose does not already make this clear. For example, if an event is taking place at 8:00 p.m., you would write, "At eight o'clock in the evening." If the event is a breakfast or a dinner, the additional words, "in the morning" or "in the evening" would not be required.
