It is an interval scale. It is not a ratio scale, the next higher level, because the zero is arbitrary and not unique from one calendar to another.

Date of birth is considered a ratio variable, not ordinal or interval. While it can indicate order (when someone was born before or after another), it also has a true zero point (the start of the calendar) and allows for meaningful comparisons of differences in age. This distinguishes it from ordinal (which only indicates order) and interval (which lacks a true zero) scales.
Sometime in the next calendar year after your birth year, you will have your first birthday. Birth year + 1 = the next year Birth year + 2 = the year after that This pattern will remain for the rest of your life. The year of your 20th birthday will be 20 years after your birth. Repeat, as necessary, until one of the years is the current one.
The longest documented time interval between the birth of twins is 87 days. This unusual case occurred in 2012 when a woman in Ireland gave birth to one twin prematurely, and the second twin was delivered nearly three months later. Such extended intervals are extremely rare and typically involve medical intervention to prolong the pregnancy of the second twin.
Year of birth is interval level of measurement; age is ratio.
The interval between each kitten birth is typically around 15-30 minutes.
The typical interval between the birth of kittens in a litter is usually around 15-30 minutes.
It is the average interval of time between the birth of parents and the birth of their offspring,

Without referring to twins, Jayne Bleackley is the mother who holds the record for the shortest interval between two children. She gave birth to Joseph Robert on September 3rd, 1999, and Annie Jessica Joyce on March 30th, 2000. The babies were born 208 days apart.

Yes it is possible although really its only one birth but with a large interval
The year is interval scale (no natural zero); your age is ratio.
