From what the Imam just rightly said, only the celebration of Eids is the time when the Taipei (Taiwan) Govt. allows them to slaughter or sacrifice their animals, only at the Grand Mosque in Taiwan. These memorable days marks the Muslims celebration of Eid-ul-Fitr and Eid-ul-Adha, Muslims commemorate and remember Abraham's trials, by themselves slaughtering an animal such as a sheep, camel, or goat This action is very often misunderstood by those outside the faith. Allah has given us power over animals and allowed us to eat meat, but only if we pronounce His name (To make our food Halal) at the time of taking life. Muslims slaughter animals in the same way throughout the year. By saying the Name of Allah (Bismillah) at the time of slaughtering, we are reminded in that way that life is sacred.
As the majority of Muslims gathered every Friday (to pray Friday Prayers known as Salatul Juma). This is the only time when you can buy halal meat imported from Australia and New Zealand as the imam said. Friday, is a religious festival for the Muslims.
In this holy day, the Muslims gather at the mosques at noon time. They listen to the khutbas (Speeches made by the Imam). Then after the prayers, most of the people go to that restaurant to buy that halal meat and halal foods sold at that restaurant only on Friday noon.
