Ted zacina to?

[AgnusOinas]

No. "Teď to začíná" or "Začíná to teď" are the normal word orders.

"To začíná teď" or "To teď začíná" in some uncommon occasions.

Your word order only works if the sentence continues: "Teď začíná to, na co nejvíc těšíme." (lit. Now begins what we're looking forward to the most)
