starting from or starting from

Yesterday, Ang's lawyer, Senior Counsel Davinder Singh, asked the court to defer the sentence, saying his client needed time to get advice on the matter. Ang is out on $250,000 bail. If he does not appeal, he will start his sentence on Friday next week.

The Singapore Dental Council disciplinary committee has suspended him from practice for a year, starting from May 11, for submitting the false claims.

Besides Goh, the clinic's practice manager Yeo Meow Koon, 47, and dentist Daniel Liew Yaoxiang, 36, are also accused of conspiring with Ang to cheat patients. Their cases are pending.

Is "starting from" correct or should it be "starting on"?

Thanks.
