'feiern' and 'begehen' can both mean that you mark or honor a special day or occasion. 'feiern' is the normal everyday word and often sounds joyful: you think of guests, food, music, or a party. 'begehen' is more formal and fits better with anniversaries, holidays, or official events. It says more that you observe the occasion in a particular way, not necessarily loudly or with a party. Learners may confuse the words because both can be used for celebrations. For birthdays and private celebrations, 'feiern' is usually more natural; for official or ceremonial occasions, 'begehen' fits better.
