+# From Roozbeh Pournader (2005-04-05):
+# The text of the Iranian law, in effect since 1925, clearly mentions
+# that the true solar year is the measure, and there is no arithmetic
+# leap year calculation involved.  There has never been any serious
+# plan to change that law....

-# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates.
-# The Persian calendar is based on the sun, and dates after around 2050

+# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates,
+# stopping after 2037 when 32-bit time_t's overflow.
+# That cal-persia used Birashk's approximation, which disagrees with the solar
+# calendar predictions for the year 2025, so I corrected those dates by hand.
+#
+# From Oscar van Vlijmen (2005-03-30), writing about future
+# discrepancies between cal-persia and the Iranian calendar:
+# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
+# the vernal equinox and that gets so close to 12:00 some local
+# Iranian time that the definition of the correct location needs to be
+# known exactly, amongst other factors.  2157 is even closer:
+# 2157-03-20 08:37:15.5 UT.  But the Gregorian year 2025 should give
+# no interpretation problem whatsoever.  By the way, another instant
+# in the near future where there will be a discrepancy between
+# arithmetical and astronomical Iranian calendars will be in 2058:
+# vernal equinox on 2058-03-20 09:03:05.9 UT.  The Java version of
+# Reingold's/Dershowitz' calculator gives correctly the Gregorian date
+# 2058-03-21 for 1 Farvardin 1437 (astronomical).
