Thanks but... Rated 4 out of 5 stars
today is 29 Esfand 1387 but this Addon on Firefox shows me 1 Farvardin 1388.
Please dear developer update it and solve this bug.
i Like this Iranian Calendar but it seems it shows a day next instead of today date.
calendar on My Vista SP1 shows 19 March 2009 but IranianCalendar shows 1 Farvardin 1388.
