it would probably be the same nights and days
The days may feel longer after a tsunami but no, the length of the day depends on the earths rotation not tsunamis.
The Earth rotates in 1 day. The moon takes 27.32 days to rotate.
Because they are proper names that define each day of the week. No other set of words can do that.
It is very close to 1 degree per day. There are 360 degrees in a complete circle and 365 days in a year.
The length of a day would increase and the number days in a year would decrease.
In a year we have 365.25 days. Now 365 day is ok but .25 remains as it is. So every four year (.25X4) makes a complete one day. So We have February of 29 days. If you the times the .25 by four then you get a whole revolution, thus creating another day.

the has an axis and it spins on it axis 27 days so in the arctic region it may take 15 days long so that's short
Earth days are normally rounded to about 24 hours, but in fact the time it takes for Earth to complete a full rotation (i.e. a day) is 23 hours, 56 minutes and 4 seconds. A year is approximately 365.24 days.
