Some updates on the Iran DST cancellation plans for next Iranian year:

Official IR News Agency announcement: irna.ir/xjJ3TT
Iran Parliament (Majles) official announcement : shorturl.at/fhtIR

Highlights: DST will be cancelled for the next Iranian year 1402 (i.e 
2023-March-21) and forthcoming years.

Backgrounds: Iranian Parliament (Majles) had rectified a law to cancel 
DST for the current Iranian year 1401 (starting 2022-3-21) just one week 
before the new Iranian year. The government subsequently objected that 
such a rapid change of plans in a short period would be hard to 
implement and would harm financial, banking, telecommunication and other 
sectors. Due to this objection, the Iranian Guardian Council had 
returned the mentioned ratification to Majles to resolve this ambiguity.

This was reviewed today in Majles with presence of Guardian Council 
representative. It is finally decided that this law should take effect 
from next year to allow the government to update their infrastructure.

Best regards,
