تایچانق (اینگیلیسیجه: Taichang Emperor) قدیم چین ایمپیراتورو. ۲۸ آقوست ۱۶۲۰ – ۲۶ سپتامبر ۱۶۲۰ ایللر آراسیندا حؤکومت ائدیب. آتاسی وانلی دیر. وانلی اؤلوموندن سوْنرا حؤکومتی اله کئچدیب و اؤزونون وفاتیندان سوْنرا تیانچی واریث کیمی تخت و تاجه صاحیب چیخیب.
^The Taichang era should have started on 22 January 1621; however, the emperor died before the start of his era. His era name means "Great goodness" or "Great prosperity". He was succeeded by his son the تیانچی, and according to the law the Tianqi era was now scheduled to start on 22 January 1621, so that the Taichang era would never exist in practice. In order to honor his father, the new emperor decided that the Wanli era would be considered ended since 27 August 1620, the last day of the 7th month in the Chinese calendar. The period from 28 August 1620 (1st day of the 8th month, which was the day on which Taichang had ascended the throne) until 21 January 1621 would become the Taichang era, enabling this era to be applied for a few months. Thus, quite an extraordinary situation resulted from this choice: the 7th month of the 48th year of the Wanli era was followed by the 8th month of the 1st year of the Taichang era (the 1st year of the Taichang era, in fact the only year of the Taichang era, lacks its first seven months), then the 12th month of the 1st year of the Taichang era was to be followed by the 1st month of the 1st year of the Tianqi era.
