A portable sundial, also known as a travel sundial, is a sundial that cannot be fixed or mounted. Stationary sundials usually measure the hour angle of the sun directly, and must be aligned with the points of the compass. Portable sundials are mostly elevation sundials, with which the elevation angle of the sun is measured and is indicated after evaluation with the as known necessary declination, respectively the year date of the sun as time. As a rule, you also need to know whether it is morning or afternoon, because a certain elevation angle can be measured twice a day.

• In excellent antique pre used condition, for age.
• 6.5 cm by 4.5 cm.
• 2.55" by 1.77".

Shipping from France

I use recycled cardboard packaging ( but in perfect condition) and new bubble wrap, for fragile items I line the box with polystyrene.

I ship items using "la Poste"s cheapest international postal rates, but this does not include tracking or insurance ( to keep the cost down as postage in France is reasonably expensive)

I only charge 1 $ over the French postal cost, this is to cover materials and time.

Tracking and insurance is an optional extra costing 3.80$ available during checkout.

International postal delivery can take from 5 days to 3 weeks, at certain times of the year maybe longer ( ie Christmas period and French summer holidays)
