My husband ordered the Perpetual Calendar for my birthday. Unlike other perpetual calendars on the market, this one offers a broad range of dates - from the year 1600 to 2799. (Several others on the market only offer a 50 year window.) In addition to its functionality, it looks beautiful on my desk - truly an elegant piece. The service and follow up from
pocketsundials.com was excellent. I highly recommend both the item and the web site.
