Learn Farsi: تو تعطیلات میرم خرید. - I'll go shopping during the holidays.

In spoken and everyday written Farsi, the present indicative (mi- prefix + present stem + ending) is the default way to talk about the future. The time expression tu ta'tilât (during the holidays) provides the future context. The formal future tense using khâhad sounds too stiff and distant for everyday personal plans.

Why use tu here instead of dar or tuy-e for 'during'?

Tu is the conversational equivalent of the formal preposition dar (in/during). While you might use tuy-e when linking to a specific physical place (like tuy-e khuneh for 'in the house'), for general time periods like ta'tilât, the simple, unlinked tu is perfectly natural in spoken Farsi.

Did we drop a preposition between miram and kharid?

Yes. In spoken Farsi, the preposition be (to) is almost always dropped after verbs of motion. So instead of the fully written out miravam be kharid (I go to shopping), you will simply hear miram kharid.

Is ta'tilât strictly plural because of the -ât ending?

While it technically carries the Arabic plural ending, Farsi treats ta'tilât as a collective noun for 'holiday', 'vacation', or 'time off'. You use this plural form even if you are just talking about one single upcoming break from work or school.
