The difference between cities can change twice a year. For example, the gap between Moscow and London is 3 hours in winter but 2 hours in summer, because the UK switches to daylight saving time.
For frequent conversions, memorize the difference between your city and your main partners. This speeds up planning.
In international projects, specify deadlines in UTC. This eliminates confusion — everyone converts to their own local time.
A conversion can move an event to a different day. If it's Monday 01:00 in Moscow, it's still Sunday 14:00 in Los Angeles.
Instead of manual calculations, use the Timezone Converter. It's faster and eliminates errors.
