In Poland, the switch to DST typically occurs on the last Sunday in March, when clocks are moved forward by one hour at 2:00 a.m. local time, effectively losing an hour of sleep that night. The switch back to standard time occurs on the last Sunday in October, when clocks are moved back by one hour at 3:00 a.m. local time, effectively gaining an hour of sleep that night.
It’s worth noting that not all countries observe DST, and some that do may have different dates for the time change.
The idea of DST was first proposed by Benjamin Franklin in 1784, but it was not widely adopted until the 20th century. The practice is now used in over 70 countries worldwide, although there is debate over its effectiveness and whether it should be continued.
Proponents of DST argue that it helps to save energy, reduce traffic accidents, and promote outdoor leisure activities during the longer daylight hours in the summer. However, critics point out that the energy savings may be minimal and that the time changes can disrupt sleep patterns and have negative effects on health and productivity.
There are also some regions that do not follow DST for various reasons. For example, some countries near the equator do not experience significant changes in daylight hours throughout the year, so there is less of a need to adjust the clocks. In addition, some regions may choose not to follow DST due to cultural or political reasons.
Overall, whether or not to observe Daylight Saving Time is a topic of ongoing debate, and it is ultimately up to each country or region to decide whether or not to participate.
