I thought they said the launch window is only open until March - how can April be feasible?

If they can't make the launch window, then when does the next window occur?

What parameters are defining the launch window?

"Regarding Chandrayaan-2 schedule, right now Chandrayaan is scheduled from March 25 to April end. Most probably, the normal targeted date is April middle," Sivan told reporters here.

I assume it's the ability to land at the target site at the end of the lunar night, so that the full span of the lunar day period can be used for the mission, before it freezes and goes offline.

Chandrayaan-2
1. Mission postponed till April (-May?).
2. Reasons: to increase robustness, reconfigure the lander, All systems needs re-development (?), requires tests.

According to Sivan, the much-delayed launch of Chandrayaan-2 - India's lunar lander - is now scheduled for March-April this year. The launch, originally scheduled for last April, was delayed as the spacecraft had to be reconfigured to bring in more redundancy to ensure safety as recommended by experts, he said.

Apologies if this was addressed up-thread or elsewhere on the forum...

Would not a fundamental change of LV require at least some re-testing of the payload towards re-certification for launch:
For example--vibrational/acoustical testing?

That would explain some of the delay?
