Muslim holidays & symbol
Question

                Do Islams have certain holidays that christans don't if so what are they?
What is your holy symbol like ours is the cross, do you have a specific symbol?
Praise be to Allah.Muslims have only two Holy days to celebrate. The two
    Holy days are Eid Alfitir, which follows the holy month of Ramadan, and Eid Aladha, which
    is in the Hajj (holy pilgrimage) season. Muslims celebrate Eid Aladha by slaughtering a
    sheep. The slaughtering of sheep is done in following the footsteps of Prophet Abraham
    when he was ordered by Allah (God) to slaughter his first child, Ishmael. When he told his
    son about it, his son told him to carry on with the order of Allah, and that he will be
    obedient and patient. As Abraham was tempting to slaughter Ishmael, Allah gave them a big
    and fat sheep to slaughter instead. The sacrificing of a sheep has become a ritual for
    Muslims every year in remembrance of the obedience of Abraham and Ishmael, peace be upon
    them. Our celebration of this day and the slaughtering of the sheep are in compliance with
    the teachings of our Prophet Mohammad, praising and peace of Allah be upon him. Only
    Muslims celebrate these two days, while at the same time, Muslims do not celebrate the
    Christian holidays.
    As for the symbol, Muslims worship Allah (God), therefor they reject
    any kind of idol worshipping. We believe that Christians believe in the cross to be a
    symbol of their God, or the so claimed Son of God. They seek blessing and protection from
    this cross. Muslims seek protection and blessing only from Allah, that is why we do not
    have an Islamic symbol as the Christians cross. Some Muslims have invented the
    symbol of a crescent to counter the cross, but this is not authentic and it is considered
    as an innovation in Islam.
