For the month as a period of time, use 'im Februar' (in February). For an exact date, use 'am' before the day, e.g. 'am 10. Februar' (on February 10).
Im Februar ist es in Deutschland oft noch sehr kalt.
In February, it is often still very cold in Germany.
If you want to give an approximate time in the month, you can put 'Anfang' (beginning), 'Mitte' (middle), or 'Ende' (end) directly before 'Februar' (February). In this case, you do not need a preposition or an article.

Feb.
'der Februar' and 'der Feb' mean the same month. 'Februar' is the full and normal form and fits in almost all situations, especially when speaking and in complete sentences. 'Feb' is an abbreviation and is more likely to appear in calendars, lists, notes, or short date formats. They can be confused because both point to the same month. For clear normal language, 'Februar' is more natural; 'Feb' saves space and feels short or note-like.
