Requested move

The following discussion is an archived discussion of a requested move. Please do not modify it. Subsequent comments should be made in a new section on the talk page. No further edits should be made to this section.

The result of the move request was: Not moved. Not sure how the Template:Asia in topic is related to this since that template doesn't have a link to this, but if there is such a problem, the template should be fixed rather than renaming the article. ≈ Chamal ^talk ¤ 07:40, 14 March 2010 (UTC)

Iran Standard Time → Time in Iran — Use old name which was used by User:Tobias Conradi, otherwise Template:Asia in topic is broken. TimeCurrency (talk) 19:11, 6 March 2010 (UTC)

• Strong oppose This is not about time in Iran, it's about Iran's timezone. I see nothing about solar time, traditional methods of dating, Zoroastrian calendar in this article. 70.29.210.242 (talk) 08:18, 7 March 2010 (UTC)
• Oppose - per 70.29.210.242; this article is congruent with Eastern Standard Time or Coordinated Universal Time. Parsecboy (talk) 16:39, 8 March 2010 (UTC)

This article discusses both Standard Time and Daylight saving time, so the lemma should be (harmonized to other articles titled "Time in Xyz" Category:Time_by_country) by moving to Time in Iran.--Bernd Rohlfs (talk) 08:19, 6 April 2026 (UTC)

Coherence

I do not find the second paragraph in the introduction section really relevant to this article: "Between 2005 and 2008, by decree of President Mahmoud Ahmadinejad, Iran did not observe daylight saving time (called Iran Daylight Time or IRDT).[1][2] It was reintroduced from 21 March 2008."

This text looked to be highly relevant back then when this rule was applied (during the years 2005->2008), but at the moment it looks more like a piece of news or historical information which is not cohesive with the main text of this article anymore. — Preceding unsigned comment added by Mkiaeeha (talk • contribs) 16:35, 9 December 2015 (UTC)

Point of change from Tehran time to UTC+03:00

The tz database of IANA bases on the research of Thomas Shanks. Shanks points the change to +03:50 on 1. January 1946 an. From the discussion at Paul Eggert :

From Roozbeh Pournader (2022-05-30):
Here's an order from the Cabinet to the rest of the government to switch to
Tehran time, which is mentioned to be already at +03:30:

Just in case that goes away, I also saved a copy at archive.org:
https://web.archive.org/web/20220530111940/https://qavanin.ir/Law/TreeText/180138
Here's my translation:
"Circular on Matching the Hours of Governmental and Official Circles
in Provinces
Approved 1314/03/22 [=1935-06-13]
According to the ruling of the Honorable Cabinet, it is ordered that from
now on in all internal provinces of the country, governmental and official
circles set their time to match Tehran time (three hours and half before
Greenwich)....
I still haven't found out when Tehran itself switched to +03:30....

From Paul Eggert (2022-06-05):
Although the above says Tehran was at +03:30 before 1935-06-13, we don't
know when it switched to +03:30.  For now, use 1935-06-13 as the switch date.
Although most likely wrong, we have no better info.

So the change took place in 1935. Unclear is the exact date. Maybe at the year change of the iranian calendar or another day. --Bernd Rohlfs (talk) 08:13, 6 April 2026 (UTC)
