# Latvia
-# From Paul Eggert (1996-11-22):
-# Rules after 1991 are by extension from Shanks. They contradict
-# IATA SSIM (1992/1996), which claims Latvia uses W-Eur rules, but
-# Peter Ilieve's relative writes that Latvia switched in September this year,
-# so we'll assume that the old C-Eur-style rules still apply.
+
+# From Liene Kanepe <Liene_Kanepe@lm.gov.lv> (1998-09-17):
+
+# I asked about this matter Scientific Secretary of the Institute of Astronomy
+# of The University of Latvia Dr. paed Mr. Ilgonis Vilks. I also searched the
+# correct data in juridical acts and I found some juridical documents about
+# changes in the counting of time in Latvia from 1981....
+#
+# Act No.35 of the Council of Ministers of Latvian SSR of 1981-01-22 ...
+# according to the Act No.925 of the Council of Ministers of USSR of 1980-10-24
+# ...: all year round the time of 2nd time zone + 1 hour, in addition turning
+# the hands of the clock 1 hour forward on 1 April at 00:00 (GMT 31 March 21:00)
+# and 1 hour backward on the 1 October at 00:00 (GMT 30 September 20:00).
+#
+# Act No.592 of the Council of Ministers of Latvian SSR of 1984-09-24 ...
+# according to the Act No.967 of the Council of Ministers of USSR of 1984-09-13
+# ...: all year round the time of 2nd time zone + 1 hour, in addition turning
+# the hands of the clock 1 hour forward on the last Sunday of March at 02:00
+# (GMT 23:00 on the previous day) and 1 hour backward on the last Sunday of
+# September at 03:00 (GMT 23:00 on the previous day).
+#
+# Act No.81 of the Council of Ministers of Latvian SSR of 1989-03-22 ...
+# according to the Act No.227 of the Council of Ministers of USSR of 1989-03-14
+# ...: since the last Sunday of March 1989 in Lithuanian SSR, Latvian SSR,
+# Estonian SSR and Kaliningrad region of Russian Federation all year round the
+# time of 2nd time zone (Moscow time minus one hour). On the territory of Latvia
+# transition to summer time is performed on the last Sunday of March at 02:00
+# (GMT 00:00), turning the hands of the clock 1 hour forward. The end of
+# daylight saving time is performed on the last Sunday of September at 03:00
+# (GMT 00:00), turning the hands of the clock 1 hour backward. Exception is
+# 1989-03-26, when we must not turn the hands of the clock....
+#
+# The Regulations of the Cabinet of Ministers of the Republic of Latvia of

# of October.... The law is the same for March and October.
+# (1998-09-29):
+# Because of the drought this year, the government decided to go into
