Potty training a puppy at night. Puppies vary in how long they can last at night without a wee. Many pups are nine or ten weeks old before they can last all night (say around midnight until 6 or 7 am) without a wee. Some pups are even older and a few pups can last six or seven hours from around eight weeks old.
In most places, two high tides and two low tides occur daily. Tides happen because the moon's gravity is pulling on the Earth and its oceans. The oceans are fluid and can move more than the land, so they move towards the moon.
- Other areas experience a semidiurnal tide with two high tides and two low tides each day. When the water levels of the two high tides and of the two low tides are unequal, the tidal pattern is called a semidiurnal mixed tide that indicates the presence of combined diurnal and semidiurnal tides.
