    These are both great freeware that you can download to answer this and many more questions that you have about the cellestial targets in your sky. Enjoy

    Because of the Philippines being close to the equator, most of the sky is visible at one time or another through the year. Only the far southern sky is never seen from your location. You will find though that most constellations are not circumpolar, or above the horizon all the time due to your low latitude. Unlike the Unites States where I live, you will get an excellent view of many southern constellations such as Centaurus, Sagittarius and Sculptor.

    Pretty much none. Constellations that can be seen year-round are known as circum-polar constellations, but you can barely see the north pole star Polaris in the Philippines at 13 degrees latitude. So your only possible circum-polar constellation is the Little Dipper, or Ursa Minor – even Ursa Major will dip below the horizon on occasion.

    Your question can be interpreted two quite different ways, which is why the answers are so different. Eri and I assumed you were asking which constellations are in your night sky all year round, in other words which constellations are circumpolar from your latitude, and the answer is almost none: just Ursa Minor is above the horizon all year long, every night.
    The others assumed you were asking what constellations were visible anywhere in the sky at all times throughout the year, and the answer to that question is nearly all of them, except for constellations very close to the South Celestial Pole which never rise above your southern horizon, mainly Octans.

    All of them. However, the polar constellations like Ursa Major in the north and the Toucan in the south might be difficult to view because they will be constantly riding the horizon.
