If the Tardis is in the time vortex, there isn't a real تاریخ of birth. So I guess they would go with the تاریخ on the planet of origin of the parents the اگلے time they visit it (minus the time they spend inside the Tardis since the birth).
Well I guess if آپ are on a planet آپ would take the تاریخ not the year. Then آپ just gauge time spent on the TARDIS. I would think that no matter where آپ jump to یا where آپ go in time that a دن is a دن and a سال is a year. If born IN the TARDIS...Well They have ways to find out the date. So ...What if they are born ON the TARDIS...Well now my brain is broke so I can not go on trying to answer!!!

Actually, since a دن is measured سے طرف کی how long the Earth takes to spin on its axis, and a سال سے طرف کی how long it takes to orbit the Sun, days and years will be different on different planets. For example, a سال on Mars is almost double the length of a سال on Earth.
