Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

Avoid direct calque 'время открытия' for one-off events; use 'время начала' instead. For regular business hours, 'время открытия' is acceptable, but 'график работы' or 'часы работы' are more common.

Common Mistakes

Using 'opening time' for a one-off ceremony (use 'opening ceremony time').
Confusing with 'opening hours' (which refers to the duration of being open, not the start point).
Incorrect preposition: 'opening time at 9' (use 'opening time *of* 9' or '*is at* 9').
