This timezone does not observe daylight saving time so the time difference always stay the same. You however need to pay attention to if the other time zone is observing DST as this will make a difference.
IST can also refer to Irish Standard Time or Israeli Standard time, but most of the times it is India that is being referred to – just make sure to double check this before you send that calendar invite!
CET is, as the name implies, the time zone for Central Europe. Important to note is that in summer Central European Time becomes CEST, which stands for Central European Summer Time. In practice, “Central” means “Western” as Central European Time includes everything from the Nordics to Spain. Note that Portugal and the UK are not on CET but instead observe GMT and that Eastern Europe (every country from Finland and South) observe Eastern European Time.
All countries in Western Europe, except Portugal and the UK, observe Central European Time. This includes Germany, Sweden, Italy, Spain, Croatia, Montenegro and Gibraltar to name a few.
The list is long but includes Berlin, Oslo, Madrid, Rome, Tirana, Amsterdam, Paris, Warsaw, Bern, Geneva and Copenhagen.
Daylight Saving Time is applied in Central Europe/Western Europe. CET in that case becomes CEST – Central European Summer Time and is one hour different. CEST is observed between the last Sunday of March and the last Sunday of October.
