There is no time difference between Shenzhen and Singapore. Both cities use UTC+8. Shenzhen uses China Standard Time (CST) while Singapore uses Singapore Standard Time (SGT). When it's 12:00 PM in Shenzhen, it's also 12:00 PM in Singapore.
Neither China nor Singapore observes daylight saving time, so they remain synchronized year-round.
Any time works! Since both cities share the same timezone, you can schedule calls during standard business hours (9:00 AM - 6:00 PM) without any time conversion needed.
Shenzhen and Singapore are both major tech and business hubs in Asia. Many Chinese tech companies have expanded to Singapore, and many Singaporean companies have operations in Shenzhen. Direct flights connect them in about 4 hours.
