Monstera deliciosa
Monstera has big leaves that lose a lot of water in bright light, but a thick root system that rots if kept wet. Water deeply, then wait for the top inch or two to dry.
Short answer: for a monstera, with the starting settings below (an 8 inch pot with a drainage hole), check the soil about every 6 to 9 days in spring and summer and every 9 to 13 days in winter, and water when the top inch of soil is dry. Give it a full drink until water runs out the bottom.

Water when the soil reaches this point
How it shifts through the year
Check the soil about every 6 to 9 days in spring and summer and water only when the top inch of soil is dry. In winter, growth slows and soil stays wet longer, so expect roughly 9 to 13 days between checks. Always confirm with your finger first.
Water slowly until water runs out the drainage holes, then empty the saucer within an hour. The right amount depends on pot size, so go by drainage and how dry the soil is, not a fixed measure. With big leaves and a thick root system, a deep soak less often works better than small, frequent splashes.
Bright, indirect light dries soil much faster than a dim corner. In low light, wait longer between checks, because the plant uses less water.
Yes. Growth slows with shorter days, so the soil stays wet longer. Keep checking by touch instead of switching to a fixed winter schedule.

Estimates use rules of thumb. Always confirm with your finger: push it about an inch into the soil before you water.
