Denní světlo šetří čas, DST

Daylight saving time (DST) or summer time (see Terminology) is the practice of advancing clocks during the summer months that have more daylight so that people get up earlier in the morning and experience more daylight in the evening. Typically clocks are adjusted forward one hour near the start of spring and are adjusted backward in the autumn.
