Nadir - I should have given an example. Does that means that I fast one day and the next day I get the opportunity to make up what I lost?
No, this use of the word "other" does not
mean "every second day".
It means every day of the week except Fridays (when abstinence from flesh meat is mandated) and Sundays* (which are not counted in the 40 days of Lent).
So, Monday, Tuesday, Wednesday, Thursday and Saturday count as fast only days. Friday and Ash Wednesday count as days of fast and abstinence.
* Of course we don't "pig out" on Sundays, as "pigging out" is the sin of gluttony any time of the year.
Do you have access to a traditional priest? If so, you should check with him.
If you don't, then I'm sure somebody here could give you the details of how to make contact with one.
