However, the tidal bore in Qiantang River must meet three conditions at the same time: first, it must be "new moon" (the first day of the China lunar calendar) or "lookout" (the sixteenth lunar calendar), that is, the earth, the moon and the sun are connected in a straight line; Second, this "new moon" or "hope" must be closest to the "autumnal equinox" solar term (around September 23); Third, this "new moon" or "look" must happen when the moon is closest to the earth (last year was September 17, when the earth and the moon were closest). Therefore, the best time to watch the tide in Qiantang River is before August 18th of the lunar calendar every year.
